Hey dude! I just studied at high school, and now just study it from learning the mechanics of cryptography! I don’t quite study maths, but more numbers/geoemtry/prime numbers! I don’t have uni degree or any of that, but I was running a bitcoin co and realised basically if our cryptography breaks we are sfrewed so from a security perspective I focused on the security of the numbers and if it is strong or is it a dependancy that can lose our customers funds. Basically just studied it because it was a dependancy for our infrastructure and that is a possible vulnerability. So studied to make sure it wasn’t all Swiss cheese-y and a risk to our customers! Sorry for the long message but hope that gives context!
