Its absolutely gambling, theres no way even a good player wont have a day he is destined to lose because the cards dont come.   You cannot bluff everything, its a stop gap.   Im nothing close to good at Poker but I just wait for other peoples mistakes, problem is if you never have good cards which is totally possible then you lose the game that day.   Poker you win one day and always keep some because its going to be a loss another day you play, gambling overall is like that handling the loss is part of the game.
