Of course, you can win in gambling all of us one time or another experienced winning in gambling, but we cannot win all the time and we cannot expect to win even though we want to win, because we do not have control of the outcome, we cannot win in gambling all the time but we can enjoy playing every time.
My simple explanation why we don't win all the time or even most of the time is because of the house edge, and the fact that we cannot eliminate that, we will continue to loss. We should learn through our experience, money is important so the moment we start gambling, we should already convince ourselves that the amount we risk is something that we can afford to lose, that's the right words, not willing to lose as no one is willing.
Or if are lucky that they and was able to overcome the big odds against you, then you need to exit and not to play and enjoy your winnings.
The more time to spend, high chances that you will loss everything that you should have won already. This is the part that I learn many many years ago, not to chase loss and not to chase more money.
