If a gambler has not enough patience in gambling he might end his day so badly. Bad temper, disgust and disappointment will swallow his head the whole round and it may result in having bad decisions in the long run. That is why we need to be physically and mentally fit when gambling to enjoy it and possibly beat the game.
Though I understand that sometimes patience is important (specially for sportbetting), I still believe that luck is more important than being patient while gambling. I don't know.
I could imagine some inpatient gambler using the auto-betting feature of the casino while playing dices or Plinko, because in his head, he wants to make money as soon as possible or wants to get a good win as fast as possible. In reality, that kind of strategies will only help to empty his pockets even faster than he ever expected to happen.
But let us not forget that gambling is mostly about luck, if someone has enough luck in a single session in dices, Crash or plinko, then that person does not need as much patience as one assumes, really. I would exchange patience for luck at any time, if I could.
