Lol. People always want to console themselves some of the time, but the thing with gambling is that as long as you do not pay so much attention to winning at all cost, and you already know that it is just a game of chance which you either win or lose, then, when you lose at the end, the best thing you will just do is to accept your fate and move on which instead, some people tend to take it personal.

Practically, for those who have been able to settle their mind that they are just paying to have fun and place a limit for themselves, losing will not be a problem, which is what I am assuming he is trying to say.
