Core gamers play games regularly, does not matter the type of game. I am not talking about casuals who get addicted to a game like candy crush though or a gamer that plays one MMO and nothing else. These are gamers in a sense, but a core gamer is someone who takes gaming as a whole a hobby and plays a multitude of games base on what they like.
No you do not have to play EVERYTHING to be a core gamer, but someone who ONLY plays Mario and Zelda or someone that ONLY plays battlefield or CoD is not a core gamer.
