Yes. I'm self taught. Plenty of self taught people at Amazon, with non-CS degrees, or no degrees at all. That definitely won't be a blocker.

My advice would be to not try to seek satisfaction from "earning as much as possible"... because "as much as possible" is an unreachable destination. I worked with lots of unhappy people earning $350K/year because they felt they should be doing $500K. How do you think they'll feel once they're making $500K? I bet they'll still be miserable because one person they know is their age and making $600K. And so on. Same with promotions and job titles. Once you clear a certain level of financial security (bills on autopay, some savings), more income stops mattering for satisfaction.
