Urgent career help needed

Hello everyone
So I will just get into the point, from the age of 9 I loved the idea of selling stuff to people and the idea of business and finance as a whole, which i ran an online business and made over 5 figures at 13.
However growing up i liked aspects of computing and especially cyber security and decided i want to persue this path at university, i currently am a year 13. For context I have 2 A*s predicted and 2 A predicteds
Now, when i applied i didnt apply to oxbridge/imperial or other competitive universities due to my very bad gcse results since i didnt take them seriously because nobody told me to, well not bad but i had 1 9 mostly 7s a few 6s and a 5 as my results
Up to this point i wanted to persure cyber security however i realized the path i want to persue should be a mix of both because i love doing those 2 things all together
I have already applied to university, and the course computer science for most.
My goal is not to be something like a quant because I do not like maths that much + i dont take further maths. Im not genetically talented or anything like that but maths was always not too difficult for me.
Can anyone please suggest me a course thats relating those 2 things and potentially allow me to have a very good career in the future, right now im considering taking a gap year, potentially taking further maths in the gap year and applying to oxbridge/imperial to study computing/econ etc, stuff to do with business and computing.
And also my last question was how likely am i to get into oxbridge/imperial with those gcses OR should I even consider this as a whole, assuming i achieved 3 a*s + a at alevels, i take maths cs chemistry and spanish
Im a contexual applicant.
