One of the reasons why I would quite agree with your opinion about us who will never be able to beat the dealer is because after all the dealer creates and organizes all the games provided in a flatfoarm and we are nothing more than guests who come occasionally without knowing about the system or rules that are applied by the dealer in each game to make gamblers lose, and this is the reason why defeats occur more often than wins and also as you said where maybe I will also clearly agree that this is the reason why the dealer always wins.
This means that I think only the dealer knows about what strategies can beat the system they apply in a game, so I think it's better for us to focus on risk management rather than keep thinking about winning, because after all the victory has been arranged, so it's best to think of various ways to keep us safe and away from various bad possibilities.
Even if a person knows the games they are playing inside out, it makes not difference at all because what matters is your luck at the time, and since the house edge is in favor of the casino, if you play for long enough you are bound to get negative results, with only a few lucky gamblers being able to obtain positive results, however the good thing about all of this is that unlike other activities in which our progress and achievements are everything, when it comes to gambling the only thing that matters is if we obtained any entertainment out of it, and if you did so responsibly then it does not matter if you lost a small amount of money.
