Is it worth studying higher mathematics?

Question

Mathematics

19 years old, law faculty, not going to code
. I have a business that I earn money with, I don’t really need math with it (yet), but I got a feeling that it’s better to study for future development. So I thought to start first with something in common, and then try into probability theory, statistics, game theory. True, since it will take me a lot of time, I can’t decide if it will give any profit?
PS Regarding the theory of probability, statistics and game theory, I took this from the programs of universities that study finance, economics, if there is something else I will be grateful for the information

Answer 1

In everyday life, a dense knowledge of the school course is enough. And for development, I would advise you to solve logical puzzles.

Answer 2

Probability theory , matstat , game theory - can be applied in everyday life and in economics in particular.
If you go through the top without studying proofs of theorems, it won’t take much time.
If with proofs, then it’s better to take a tutor and go through everything with him back to the topics that are forgotten, down to linear algebra

Answer 3

Basically no. Unless, of course, you want to go to the academy, etc.

Answer 4

Not necessary. I speak as someone who receives a specialized education. For your lesson, I assure you, school mathematics is enough. If you develop strongly in your niche, find a specialist.
Independent study to some sane level will take 4 years of work, no less. It's not going deep.
