The expectation that they've got the beginner's luck, that's not true, not everyone has that in them and the reason why that kind of belief propagated is because casinos and other gambling business want to do something about keeping the reins on the beginner gamblers, that's the only way that I can describe it. They want people to think that they can exploit this non-existent thing to try and gamble even more and then at the end of the day, it really was just a one lucky play and that there's no way that you can be on a hot streak just because they tell you that you were lucky as a beginner. To avoid this kind of thing, maybe just being a pragmatic person and you would be fine, that way, you don't have to worry too much about things that doesn't affect your game or yourself, most beginners are advised to read this kind of threads because it basically teaches you what you need to know because it's the people that have experienced it that's talking about it.
Agree that casinos are responsible for this so-called beginner's luck and even if not all newbies are covered with it but at least many of them are. For me, it's not a big deal if they will keep on considering it as a beginner's luck but as long as the effects are still the same.
Even let say a newbie gambler will have a strong belief like that, that they think it's exploitable, I won't still think that they will continue burning more money if the early results they get are negative. And at the same time they will realize that they are wrong and they can also blame the casino for having that false belief. This thread has a newbie word on it, so newbies are more likely reading this.
But I think that, of course, any game that we are accustomed to consider a game of chance with provable fairness does not pay any attentionn to which player is playing it. And in general, apparently the newcomer’s luck is largely an advertising option for additionally attracting clients to the gambling industry. But still, the idea that beginners are lucky is too widespread in the gambling industry. And even often experienced players, if they lose to an opponent who can be considered a beginner, justify their failure in the game precisely by the fact that the opponent is a beginner, and they, these newcomers, assholes, are always lucky. This is also a very nice argument to justify a loss for an experienced player.
And of course, to calm yourself down after an unsuccessful game with a newcomer.
