But you'll end up getting a whole new vocabulary when you join a new industry. What you did at uni was practicing learning new vocabulary and models. I would say as far as something like math appears to be foundational, what it really makes you practice is precision thinking: this thing matters, this other thing doesn't. One thing that might convince you is that when you look at math the subject itself, how many people who were good at applied math like calculus and PDEs actually know anything about mathematical foundations like ZFC, Gödel, and that type of thing?
