You're right, there are gamblers who think that they have gone roo far in gambler and for that they know how to go about the gambling thing in the aspect of getting back their loses but thats funny because, if as a gambler, you weren't able to win earlier, you later think that you can win all your lose may be because of the deceit in your mind then serious losing awaits such gambler, the best way to go about gambling is by allowing by gone to be by gone, letting go of the past, concentrating in things that are about to come nothing more, not all gamblers falls to this cheap trap, I believe that there are many responsible gamblers out there who won't dance to this tune.
If a player has lost before, then it is useless to wait for something to change in the future, for this you need to change your approach, strategy, possibly bankroll management and much more. And if you just wait for it to change itself, then this will definitely not happen, because nothing will change by itself. Sometimes players after a loss try to increase the deposit and try again, but this is a sure-fire loser, because first you need to change something, because under the same conditions the result will remain the same.
