Yes and that's why we see them playing as if they don't feel any burden or tension in themselves even though they bet with a very large amount, and I think from there we can already know a little that actually the gambling activities they do are not real in the sense of gambling not with real money as you might think. Streamers play with demo accounts where the balance in them is only in the form of numbers and not real money that can be withdrawn.
On the other hand, logically if it is a real account and if they can really generate a lot of wins then why do most of them always do the same thing as doing shows? I think from here alone of course this raises suspicions that make it look even more unrealistic.
Most of them use demo account that's why we don't see those streamers doubt of feel something bad happen when they lose their huge bets placed. And its pretty much obvious on schemes they do that's why I don't usually watch those kind of streamers especially if I see that there's huge balance on their account and they play common games which have demo account feature since we provably cannot get any entertaining factor with those people.
For sure if they use real money for sure that they would never place any random huge bets and they would be more careful placing it. For streamers its all about show and to hype people to try the casino they are promoting so we must be careful with them.
Often I also find shows like that when I'm playing social media and of course we are the same friend in the sense that I'm not too interested in seeing it, although for some people it really looks tempting but for me it's very boring, I don't condemn gambling but I'm quite annoyed when I see people who try to trap the audience with something that looks tempting at first.
