When there is a player who has a strategy to win and it definitely happens then in other words he can get profit in the long term, but that is impossible, besides the casino in my opinion will be suspicious or take other actions to pay attention to the player who can always get profit in every bet he makes. This will definitely happen because the casino will definitely not let that happen which will definitely attract the attention of the casino. It is not a problem when many people lose money because it is a natural thing to happen because the goal of the casino is to seek profit from the many people who visit the casino, so even though there are people who will win but not everyone can get it as well as big wins or jackpots.
I completely agree with you that gamblers do not use any strategy for their long-term winnings and they do not see justice with their money. They lose most of the time and if luck is too kind, then maybe after a long time the chances of winning a jackpot are very limited. The underlying algorithm of the casino is developed and operated in such a way that the developers get more profit. With all the activities to attract gamblers, the developers get extra winnings. They give you limited bonuses for various celebrations like Christmas or New Year but they do it for their own profit. I am worried about those new players who mostly choose the wrong casino, watch social media ads and make deposits to get a source of income which is a possibility of losing their money.
People who chase fortune usually don't care about anything other than the gambling they do, including their finances and the time they spend gambling. People who focus on gambling are people who I think no longer see the risks of gambling, although sometimes they can realize it but most likely they will just ignore it and focus on gambling again which they do to get the big win they are chasing.
You have good empathy by worrying about other people, I myself don't care as long as it's not someone I know even though sometimes I feel sorry when I see them but when they have trouble because of their gambling it is a risk so they have to accept it, for those who choose the wrong casino maybe they can look for a casino that has a reputation moreover currently there are so many online casinos operating we just have to be smart in choosing the casino.
