Want to pursue a career in concept art for games - what path to take?

First time making my own thread here so please bear with me :P
Tried to word this as concisely as I could but it turned out long so if you want to see my main questions skip to the end.
Currently in Year 12 and therefore looking around at what options I have after sixth form - leaning very heavily towards university, but the prospects of some very cool looking art schools abroad have also caught my attention...
Like the title of the thread says, I want to work as an artist in the games industry. My long-term goal is to become a concept artist (preferably in games).
Having done some research, I understand that it is very rare for fresh graduates to immediately be considered as concept artists because this is a very important role in the production pipeline. It appears to be a much more competitive position to attain because of this (only a small number are needed in comparison to modellers etc.). As such, it is preferable to "work your way up" in order for the place you are working at to build trust and confidence in your skill before they potentially promote you to this role.
Since this is the case, I have thought that perhaps studying a Game Art course in the UK would be better. The universities I have considered so far which have these courses, and probably will stick with, are (in no particular order):

Any other recommendations are welcomed but I was really impressed by the work coming out from all these places. I also have confidence in their accreditations (Screenskills/Rookies etc.) and generally, the teaching seems very good.
It was actually doing some digging on The Rookies website alongside some prior knowledge I had from following various concept artists that I came across the art schools abroad that I mentioned caught my attention - to name a couple, FZD in Singapore and New3dge in Paris. Both these places produce amazing works from students and are also quite reputable internationally from my understanding (the former being founded by a well-known concept artist of the industry after all, though I am aware Herts has been quite successful in recent Rookies rankings of last year too!). Having spoken to my parents about my interest they have told me that if I chose to go somewhere abroad they would not mind funding it (as long as it's not somewhere super expensive like perhaps the US).
I will make it clear here that I am currently leaning a lot more towards staying in the UK! I don't know if going abroad for 1 or 2 years (since these are diplomas rather than degrees) and living by myself is something I'm ready to jump into after I've just finished sixth form. It would obviously be more difficult to visit my friends and family and although I would probably make new friends and culturally enrich myself I'm not sure I'm so willing to at this point in my life. Maybe later on. If I stay here for uni (which I probably will) I do intend on doing some sort of work placement/year abroad, but I'd have settled in a little more into... life, so I wouldn't be so worried, I'd like to think.
On top of that, as if the courses here weren't tough enough to get on already, it seems as if the places abroad are even tougher. I believe New3dge only takes in 20 students per year on their international concept art course, and I'm not sure about FZD but it is a very tough and intensive one-year course so I imagine it's somewhat similar (though they have three intakes a year rather than one). I think it may be a bit too ambitious to be looking at these places right now; I cannot be certain I'm guaranteed a place here, let alone at those places. Are those schools perhaps something to consider after uni? Though would there be any point after having done so much studying already? Also, I'm really interested in the uni experience, and I'd miss out on that, even though going to a school all about art sounds like a lot of fun (though potentially stressful... the places I mentioned have many hours of work daily! It'd feel very reminiscent of my current school days.).
Putting aside the actual hurdle of getting into the places I apply for, I'm not sure which courses would actually be more favourable in terms of getting a job. The Game Art courses I feel would be more beneficial in teaching me specifically about work in games (obviously) and allow me to develop a wider range of skills regarding the game production pipeline. It is not as if schools abroad do not touch on skills such as modelling and animation, since these are things a concept artist should have some knowledge of too, but it certainly feels there is more of an emphasis on the concept art side of things (given the names of the courses compared to the ones here) whereas Game Art might give a fair share of everything. However, the concept art places abroad seem to have just as good employability rates at very big names after their courses as the courses here (which also have people going onto big names), although I assume those might not necessarily be concept art jobs initially.
Also, I am aware there are concept art courses here. However from what I have seen these courses tend to be mixed with comic art studies, which I admittedly have little interest in. These courses also seem to be more recent, so they have less... of a record, or history if that makes sense. Not that that makes them bad courses but I would trust the Game Art courses that have been around for longer more.
TL, DR; I suppose my main questions are

If you read all of my rambles, thank you for your time! Any answers you may have for me are much appreciated

I want to be a concept artist in games in the distant future. Should I study a concept art course or a game art course? Which is more likely to get me a job afterwards and why?

Continuing on from this, dedicated art school or university?

More generally, is it a good idea to study abroad or should I stay in the UK? Is it worth the extra costs?
