That was my struggle, too. Imperial College London has a small online course which covers similar topics (https://www.coursera.org/learn/multivariate-calculus-machine...). It helped a lot.

I just finished my first year in an AI bachelors, we saw Linear Algebra with basic matrix calculations and theorems, so much calculus that the notes take up 3GB space, physics, phycology and very outdated logic classes and basics to python which left many of the students wondering how to import a library

True, this was a designated resource during my studies (2020/2022), but they were post-2018.
