Getting back into CS:GO

I haven't played CS:GO in many years (last time I played was when tec-9 was still busted af) and want to get back into the game. I've been looking for guide videos on the meta and new tips/tricks/strats because I realized I don't know how to play anymore, but haven't been able to find any. Does anyone know any good CS:GO guide videos on the recent meta so I can get back?
