Are there videos to learn more advanced characters and see them played at a low skill level?

Hi! I am a new fan introduced to the game via the RHAP survivor games. i love this game and its mechanics but don’t know where to start.

when i went to the official seeming youtube channel that i found, i watched part of their new character introductions, but immediately realized i was in the deep end not recognizing most characters that were in play.

if anyone has any advice for how to learn outside of playing yourself (which i am looking into soon) i would love the help, thank you so much
