I believe that they do not affect the casino business in any way. The thing is that both hope and luck are characteristics of the game of an individual player, and since there are many players, hope and luck naturally cannot be simultaneously for all or even for most of the players. In the ideal case, half of the players can be lucky at the same time; on the contrary, failure is observed in the opposite half of the players. But it is worth adding a third side. Actually, the casino itself, which, roughly speaking, always has luck. It's just that atherwise the casino cannot exist and make a profit for its leaders. It is obvious.
So it turns out that thee are always more players in a state of failure than lucky players.
But, I repeat, the business model of the casino, as it seems to me, is not affected by such personal and purely individual streaks of luck, success, or, accordingly, bad luck and losses.
I do agree that there is nothing wrong with that, and I can understand why that would be considered a trouble if people just fall in with hope too much. You can hope all you want but that doesn't mean that you are going to get a good result in the end. I can understand that maybe some people could end up with a trouble on the long run but that doesn't mean that you are going to end up with a good result in any case.
This is why it is quite important to just let it be and forget about hoping for a better outcome, because that will not be important for you on the long run. I get that some people may want that, but most people will not have that type of good result that they hope for, hence we should not be considering that as a goal.
