Yes, it is true and I have one friend who is a gambler on slot games where he always plays by making the RTP machine as a reference or simply as you said above that when the RTP percentage on one of the games is high then they will choose or stick to the game, all of this is based on their feelings and beliefs that they think the high RTP percentage will be able to increase their chances of winning closer. Honestly, I don't really know about that, but let's think with the logic that the whole gambling is to benefit the casino and on the other hand the RTP is provided by the casino itself which means it is not a very possible thing that the RTP is manipulated? I think this is a suspicion that should be in your mind, where there is a possibility that the casino makes the percentage of the game high when in fact the game's performance is very bad.
Right, I agree with you that I don't really believe in it either, because as I said above that if we think rationally using logic then I think it's something that should be suspected and not used as a reference for choosing games, in the end you will still be able to win when you are lucky, it's that simple.
This is normal, because everyone has different thoughts and preferences, so there are those who believe in RTP by gambling and using RTP as a reference, like your friend, I think he is a gambler who can gamble calmly and confidently. in games that have a high RTP percentage. because in my environment there are people like this, when he gambles he looks for a game he likes that has a high RTP and when he finds it he plays it with confidence, and at the beginning of the game it is sometimes good so it makes him happy, but when the game starts to turn bad he stopped and exited then looked at the RTP again which showed the RTP was low and he thought that had an effect, I'm not sure about that myself, but that's humans, who have different thoughts and beliefs.
It's true, it's just a form of deception provided by the host, because it's impossible for it to be clear that it will definitely give us a win. If indeed we could win by relying on RTP then I myself, who doesn't believe in RTP, might believe it. but the reality is not like that. what happened to my friend who gambled completely believing in RTP and he never even got a big win during the gambling he did.
