And related to combinatorial math - probability is usually a required course in CS, very helpful for tons of tech jobs (e.g., quant jobs). You can actually make a decent living as a programmer by just gluing js/ruby together, since that constitutes the bulk of most programming jobs. I guess the point is that formal eduction forces you to learn advanced math, whereas only the motivated self-taught programmers learn it.
