If you mean by all their customers taken together, then you are right. But how does this apply to us individual players? It's a false statement that "no one can beat the casino". You know this, right? There are tons of examples of people winning huge amounts through gambling, so, I think, we shouldn't repeat this false statement over and over like a mantra. Leave it to dishonest journalists.
I understand what you're saying but here what I mean is about luck and as I said before that there are no guarantees.
what I say is maybe some people will disagree, but from my experience, if I tell the truth, I think someone who wins a lot of money from gambling, if you calculate the overall losses and profits, will not be equal.
like for example I bet the first day I lost $500, the second day I lost $1000 and the third day I won $1000. despite getting a $1000 win but a $500 loss.
but back to that there are no guarantees because the luck of every gambler is different and all of this depends on a commitment not to be greedy. even though someone is lucky to beat the casino make a lot of money but greedy want to earn more I'm sure he will lose even more soon and fail to beat the casino like the problem of that time a person won over $500k but wanted to win $1m and finally all his big win was gone and failed to beat the casino.
I understand, there are such cases, there are many of them, that's true. But it's not like a rule that everyone loses in gambling in the long run. It's simply not true. It's like saying that everyone who drinks alcohol becomes an alcoholic eventually. Or, everyone who eats cake eventually becomes obese.
I, for one, am in profit from gambling, especially from playing poker, but I know it proves nothing, because it's a single case. What is more important is that neither online games, nor our brains are designed so that we will necessarily lose in the long run.
