That makes sense. But for me for instance, who's trying to learn about AI and have a math background, I like courses that explain the math behind everything because it makes it easier to understand the concepts. It's also a good way to check that I understand what's going on. And finally, I find it easier to skim over a text has equations, they easier to parse for me since I'm a slow prose reader. So I can go through a text by skimming through the math, and when I stop understanding, I try to backtrack what's going on and only move on once I understand what was blocking me.

EDIT: And this applies to everything. Ex: I've been playing the guitar for over a decade but have been struggling with music theory. I've recently tried to apply the little algebra I know to it to try and find structure. I've found some really cool articles, for instance [0], and it's helped quite a bit believe it or not !! For French speakers that like music, math, and algorithms, I highly encourage a presentation by Moreno Andreatta [1] where he closes the presentation by performing a "rotation around the Do of the Beatles' Hey Jude".
