I'm an Oxford graduate (Modern History). I have practised in commercial and public law at the London Bar and internationally for over thirty years. My current practice involves international commercial disputes, and I work with lawyers from several jurisdictions.
MsSpecter22, I agree with those above who have suggested that you focus on doing the best you can at school, and do not fixate on one university, one law firm, or one type of career, in the law or not. Until you start studying law, it may be difficult for you to decide which area of the law interests you, and whether you wish to be a disputes lawyer, a transactional lawyer, and so on. In addition, which firm or chambers a young lawyer ends up at, and which area of work they start out in, depends on many factors such as market forces, and sheer luck of the draw.
It may go without saying that the practice of law is not accurately represented by TV shows and films. Being a lawyer can be enormous fun. The intellectual, moral, and financial rewards can be good. But being a lawyer also involves a lot of hard work, not all of that work is exciting, and some of it can be very tedious. Some clients are horrible people, and some types of legal practice can be ethically, psychologically, and emotionally challenging. Most lawyers don't work in gleaming city offices or swanky chambers, and many lawyers lead a humdrum life for not great money. Obtaining a place in a leading law firm or set of chambers is very difficult.
You might find that you don't take to the law when you start to study it. You might decide that you prefer to do a non law degree and then study law after your first degree. Or you might find that you delight in academic legal enquiry and wish to become an academic lawyer, or that you'd prefer training to be a barrister and not a solicitor. It's too early to know what you will think about these things when you are starting university and when you are graduating.
I add that thegeek888 is, I am sure, trying to be helpful, but he tends to give dogmatic and not always reliable advice despite having no experience of university, or of legal practice. He is, as far as I know, an A level student who hasn't yet applied to any university or worked in any legal job, and doesn't plan to apply to university until 2027. The idea of aiming to practise tax law in the hope of meeting celebrities is entertaining, but also a bit daft.
Good luck in your studies.
