ExMormon (25F) trying to break into bartending. Where do I even start?

I (25F) absolutely hate my upbringing, but I was raised Mormon and went to BYU for my first year of college. Alcohol is considered a major sin in the religion, so I didn’t have much exposure to it until after I dropped out, left the religion, and started experiencing life outside of that environment.

Since then, I’ve realized I really love vodka anything, but I don’t know much beyond that. I’m still pretty unfamiliar with brands, classic cocktails, terminology, and more, and I’d like to work my way up and actually learn.

Right now, I’m a barista at one of the busiest Starbucks locations in my state. I know that’s not the same as bartending, but I genuinely love making drinks, talking with customers, and the chaos of rushes. It made me realize I might really enjoy bartending. I also want to build a more sustainable career because even though I have two degrees, it feels like without a master’s, the pay ceiling is pretty limited.

So I’m curious, what would you recommend as a starting point? Are there solid mixology courses online? Is something like a bartending school like Minnesota School of Bartending actually worth it?
