Better To Start in January?

Not too long ago I decided that I should go to university, but I did not know what course I'd want to do or where. At that point I hadn't completed my UCAS application as I did not have my A-Level certificates from my time in the sixth form, which ended two years ago. When I got them a little while ago I filled in the information on UCAS as well as the results from my college course. Despite my poor performance in two of the courses I did in the sixth form, I am in a good position with my UCAS points as the courses I did well in more than make up for the lost points. In that regard I am probably able to go to most courses on offer, but I am still not sure what I should do. I have spent a lot of my life acting and doing acting courses, so it would be the obvious option. My cousin, however, did acting at university and it was a massive waste of time and the amount of acting roles he's had in the past twenty years can be counted on my hands despite him going to hundreds of auditions. I haven't gone to that many auditions, but I haven't had any luck even though I am a good actor. Finally, my teachers at college have told me that university acting courses are not respected anywhere near as much as drama school, and from what they've told me about drama school they sound like hell on earth, and therefore they are absolutely out of the question.
So while I'm indecisive and genuinely considering going into clearing for literally any course, I'm wondering if it would be better to go into a course that starts in January rather than next month. There are certain advantages to doing that:

That said, I have some concerns. I don't know much about these later start courses - is there a catch to starting in January?

So what do you specifically want to do after uni?
If it's in acting, you know very well that you don't need any qualifications to go into acting.
I would advise against doing any degree for the sake of having a degree. If you are not studying a subject because you love the subject, you intend to go into academic research in the subject, or the specific degree you're applying for is legally required for the role that you want to work in (e.g. medicine, nursing, architecture), then I don't recommend going to university.
If you do have a career in mind, then what is the career? If you are passionate about a subject, what are you passionate about? Also, what specific qualifications did you do at college?

I have no idea of what I want to do in life. Well, I do, but the dreams I have are extremely aspirational and unobtainable for at least twenty years or so. I have looked at jobs but the area I live in has virtually nothing going on - there aren't even any low-level office jobs from what I've seen. To simplify a complicated situation for the sake of brevity, my family does not have the money for me to take driving lessons and buy a car at the moment, so driving somewhere else for work is out of the question. That may change within the next few months, but there are no guarantees with that.
I am passionate about acting and things related to it - long term, I'd like to direct a film or write/create one. As I said in my original post, doing a course in that is not really a good idea, but there are no other subjects that I'm interested in. The reason I want to go to university, other than having a degree, is to get out of the house and effectively restart my life as it were. At this point in time I have two friends, one of whom lives in Spain and the other is going to university so I won't see him very much, and I ruined my friendships in one way or another with pretty much everyone else. I'd like to be in a different environment, to put it simply.

It's probably the problem I would tackle first. Makes more sense to get a car and learn to drive for a few thousand pounds than to spend at least £27k on a degree that might not end up getting you a job.

There are only a handful of degrees that are either legally required to helps with specific careers (e.g. healthcare, education, architecture, law, engineering). Of course, if you have no interest in those careers, then doing a degree in the related subject is rather pointless.
Most other careers you can more or less do with the qualifications that you have now (there are about 600 different careers to go into with passes at A Level).
I'd like to be in a different environment, to put it simply.
Moving to a different location would probably make more sense than just doing a degree at a uni at a different location. My go to tool for this is spareroom.com. However, I would recommend getting a driving licence and ideally a car before you do this.
Instead, have you looked into professional qualifications? I wouldn't recommend doing anything above the equivalent of NVQ Level 3 until the ELQ policy supposedly expires in 2025 - you would have problems getting student funding otherwise.
Having said that, even if you do get a degree or professional qualification if there are no jobs in your local area (and you can't relocate/travel), then you would still be in the same situation as you are now.

One thing I forgot to mention was what I got at college and in the sixth form. In the sixth form I got a distinction star in psychology, a C in art, a D in photography, and a B in my extended project. At college I got a distinction in performing arts - that course was the equivalent of three A-levels.
But to get to what you were saying, my mother has two trains of thought when it comes to university. She says that I should either do acting because I'm good at it, or I should do something that I'll be able to make a lot of money from.
Something I'd like to do is start my own business, but as I mentioned with my silly dreams, most of them would require millions in funding to get off the ground, as most of them are to do with transportation - those including (but are not limited to) starting a low-cost ferry operator to profit out of the impending collapse of P&O, starting a rail freight operator to profit off the impending collapse of DB Schenker, and manufacturing cars and other motor vehicles using non-electric alternative fuel sources. As you can tell, any of these are quite out of my league for the time being, and probably forever.
I do have one more business idea which is actually semi-reasonable: to develop a game. I have started an online course for the basics of game development but I'm really struggling with it, so I think that one may be out of the question as well. What I really need is a doable business idea based on something that I know I can do with what I have now and in the near future, rather than some big idea that would take me half my life to fulfil. As to what this idea is, I have no idea.

I don't like bumping threads but I do still want to know about the last question in my OP. If I do start in January, are there any downsides to it?

Very few degrees start in January.
Usually only Nursing.
What are you hoping to study.

Some possible degree ideas - none of these start in January - as above, that's practically unknown in the UK - but they are theatre-type courses that might appeal to you and have a better employment record than acting :
BA (Hons) Film & Television Production - Bristol Old Vic Theatre School
BA (Hons) Stage Management - Bristol Old Vic Theatre School
Theatre, Festival and Event Production – BA (Hons) – Bath Spa University
BA (Hons) Arts Management | Goldsmiths, University of London
