>>2637141very VERY VERY few youtubers actually spend any extended amount of time outside, they're mostly entertainers who barely know anything more than you do or often less producing clickbait.
the few who do know jack shit are far more specialized than "survival" channels. i could give you at least 5 or 10 good cave diving channels but i can't name a single "survival" channel worth a shit.
even if they did know anything chances are their knowledge is adapted to a completely different environment than you spend your time in.
go outside, get experience, and read books.
