Yes, you will learn to think numerically and practice applying opaque algorithms, but you’d be better off starting with basic set theory and logic and learning “real” math. Book of Proof is one of my personal favorites. Then you can move onto some Real Analysis while brushing up on Calculus, then maybe consider formal probability starting to learn the foundations
