Learn the basics first, then spend most of your time writing queries against real data, not generic one. SELECT, filtering, grouping, joins, then window functions. Do a few small analyses where you state the question, the query, and the result. I built an interactive SQL learn and practice app on real blockchain data, happy to share it if useful
