I think most user that enter casino knew already the risk since this is common knowledge that house always win. Trying their luck is one of the main reason why players keep playing despite of the low odds to win.
Anyone who disobeyed the rules of the games often lose for long term and we know that already, so when's we are invited much loses we shouldn't be that naive to keep trying our luck to see if we could break the house to win the against the casino. Knowing when to stop plays a crucial role in our gambling life but then we tends to be constantly trying to explore different strategies to see if we could at least have some luck to win game even as that the chances of losing is still higher than we expected.
If every gambler knows that we cannot beat the casino, they will know when to stop playing and quit for the day, continuing to chase loses when you are not winning can lead to regrets. There is a rule to enjoy gambling and that is to use amount that you can afford to loose because the house always wins on the long run. A lot of people gamble and a few wins, you don't know when you will be among the lucky few so it is wise to use small amounts to gamble because it is likely that you can be among the majority of losers. When you win don't regret and wish that you would have used a huge amount, if you use a huge amount after a win it is likely that you will lose your money.
