The impossible thing is that everyone is lucky enough to get a big win through the gambling they do, because if that happens then there will be a few cases of bad impacts from gambling circulating but the reality is that there are many cases that occur about people who experience bad impacts from gambling and that is because they are unlucky in their gambling but force themselves to get a win or in other words they are chasing luck which actually does not have to be done.
The house that always gets more wins than losses will certainly occasionally give big wins to its players and that is the goal is to keep them in their casino or stay in their casino if they gamble, but even so they will not experience losses because the wins obtained by the players are a small part of the profits they get.
That is normal for the house to give some wins to some gamblers, big and small.
Because if there are no gamblers that wins from them, most of the gamblers will flee from them and they're going to stop visiting them.
So, any strategy that works, it will work shortly but not in the long run.
Most likely what will happen if they do not give any wins to their players at all, then the casino may have a bad reputation and also the comments that players leave may criticize the casino, but it is also impossible for a casino to not give any wins to its players at all, it is done by casinos that really intend to deceive many people. Players also cannot fully get benefits easily even with the strategies they have.
There is a possibility that the strategy used can work, but in my opinion that is only because luck is on their side, because when they succeed in getting a win with their strategy and then practice it again, the strategy will not be able to give them a win again.
