I would also add: the above is not to say you (or anyone else) should not go to university, nor that I don't understand why you're asking what you're asking. My point is though that you're basically asking the wrong questions about choosing to go to university or not, and that if your principal goal is financial then you really aren't going to make the most of your time at uni anyway right now and you'd be better off putting it off and going later than going now. Whether that's after a gap year working, or after starting a career then deciding you want to do something different, or something between or else entirely.
The bottom line is as much as TSR likes to quibble about this and look at statistics around salaries in a vacuum, your degree subject is not really going to make or break your ability to earn. For a concrete example, consider the ever continuing obsession with computer science as a purportedly "good" "high value" degree. The reality is the labour market around the associated development and "tech" jobs is pretty bad and has been for quite a while, and while a small proportion earn oodles of money at FAANG or one of these new AI startups or some silicon valley "disruptor", the vast majority do not and will not ever go into those jobs. The gap between "highly skilled" and "low skilled" jobs for CS graduates in terms of income is one of the highest, and reflects this sharp difference in the types of jobs graduates from that same degree field can get.
Students need to make decisions on the basis of what the common outcome is - which for CS for most is probably closer to "sysadmin for regional firm" than "software engineer at google". The same principle applies to any degree, and the reality is most of them are going to have jobs and salaries that are not unattainable with often many different degree options, or even without doing a degree. A job and a salary is not a unique outcome of a degree, nor is even a "good" salary (by which I mean an actual good salary based on the real world outcomes are, not what school-leaver me thought was a good salary). Learning things which you have not have the opportunity to learn and probably won't again have the opportunity to formally study is one of the key unique outcomes of a degree.
