Expensive education isn't necessary, at least, not for me or for any of my friends.
We taught ourselves by starting at a young age, watching videos, talking with each other about it, etc.
I took some courses on Udemy for the sakes of it, and it also helped me understanding it better.
My advice: learn in practice, apply what you've learned and what you know, learn from others, etc.
I never needed expensive, regular, long education. Decide for yourself whether you need it or not.

Good luck!
