Can't anyone realize that most or maybe 95% of Einstein quotes are fake.
Maybe, but people in the know realize that Einstein used to play Lasker on occasion, and that his chess quotes are accurate.
It would be easy for him to say that it's a waste of time when he inevitably lost. He is credited with being a poor player. Even so, Lasker, Einsein's friend, was an amateur player who devoted his energies to many things. Einstein knew that, so saying that chess is a wate of time would be both insulting to his friend and inaccurate. It may be that Lasker challenged him to study more and improve and he retorted that would be a waste of time, which would be reasonable.
As some are aware, I dislike Einstein and therefore am not supporing him due to any kind of hero-worship.

Albert Einstein is credited with describing gambling as a waste of time. But it seems that he did not call gambling a total waste of time, but an activity he engaged in when he needed a break from his work.
Given his other eccentricities, this statement could be seen as a reflection on his use of time and not as a comment on other people playing the game
