Complete beginner, how to start?

Hey! recently been thinking of getting into a tcg, always been a pokemon fan but now doesn’t feel like a good time to get into it. Always really liked yu gi oh card art so i thought id get into it now, i have a nice collection of cards but know absolutely nothing about playing the game

I have a couple of structure decks (albaz strike, legend of crystal beats) and a huge bin of probably 500+ misc cards. One of the decks i have is a blue eyes white destiny, looking online ive seen people recommend getting three of them to make a good beginner deck a while back, is that still worth it?

any yt videos that are good for explaining the game to beginners?
