Popular traders (YouTubers) that aren’t actually legit?

I’m trying to soak up all the free online resources that I can to learn the basics of trading because *holy SHIT* there’s so much to learn. I’ve been watching quite a few YouTubers who put out a lot of free game and some who sell courses. My question to everyone here is have yall watched anyone who seems legit but later turns out to be a fake? As in their advice isn’t genuine and courses are a scam? Edit: how did y’all learn to trade and what resources did you use?
