Beginner question

I haven't touched a yugioh card for the past 15 years, and even back then we used to make up some of the rules lol.

I wanted to hop back and try to relearn yugioh so i can play this game.

I was wondering if this game has a decent tutorial and bots games so i can learn it,or is it too late for me to even try? Even if its too late to compete online, i can still have fun in offline pve mods if there are any.

Also can someone please quickly explain how building a deck work in this game?I still remember what some card do but i doubt that i would be able to get/chose them right from the start
