There are plenty of courses, classes, and schooling as you dewcribe, it’s just a matter of cost. A LLM is more useful for studying because it feels interactive however a lot of software development in general is applying what learned and what you need.

If you want to spend 10 years growing your career and understanding math with the help of an LLM you will work it out eventually, by gambling on your role at a company and their offering of projects.

If you want to spend 6 months - 6 years understanding the pieces you need for a professional career at various levels (hence the range), you pay for that kind of education.
