For me I really do enjoy watching some of the Locking picking lawyers content and he is an expert when it comes to picking locks!
Another few are mental outlaw (although I think everyone knows of him here) and Steven Bridges who makes videos on card counting at casinos and he shows how much he wins/loses from playing
This Old Tony - amateur machinist and pair of disembodied hands, making impeccably edited, brilliantly written content. He’s entertaining and funny. I’m not interested in machining but I’ve watched every single one of his vids.
