The standard system of a casino has no external interference from outside source like Op claims. Casino machines have been designated to work alongside the house edge, as you mentioned. The arrival of a good result can't be predicted, but things may occur differently, and the winner will accept that his friend influenced the result. However, it'll sound weird to other listeners, including the appreciated person. Those thoughts erupt in form of joy, and happiness tagged to similar reaction we had on the arrival of a friend.
But the gambler fails to forget the days he lost money, and other times when he won without the presence of his friend. People believe different things and don't care what others will say regarding their belief. Yet, looking at gambling in a more sincere perspective, nothing works adequately, like it may have been painted by other gamblers. Hence, discussing this as a proven fact, the process needs to be tried repeatedly, again and again, you'd notice the whole belief will end up as false.
There would surely be perspective on the standard system of a casino and the beliefs gamblers may hold regarding external influences on outcomes. Casino machines are designed to work in favor of the house edge, as commonly understood. When a gambler experiences a positive outcome, they may attribute it to the presence or influence of a friend. This attribution can bring about feelings of joy and happiness, similar to the excitement of a friend's arrival.But the gambler fails to forget the days he lost money, and other times when he won without the presence of his friend.

Despite the joy of winning, gamblers often remember both the times they lost money and the times they won without their friend's presence. This suggests a complex interplay between beliefs, experiences, and outcomes in gambling. People hold diverse beliefs about gambling outcomes, because there is subjective nature of gambling experiences and interpretations. Experiences, and skepticism surrounding gambling outcomes emphasize the importance of critical thinking and empirical evidence in evaluating the validity of such beliefs.
Having beliefs on gambling is taking away the concept of the game, and leads to the problem with gamblers, today. They already believe gambling would outsource wealth on their behalf. Hence, see it as a disobedient to quit in times of trouble. Players, recently, don't give up on their beliefs easily. And that has affected the way gamblers think and behave. As a strong belief on a platform like gambling, seems unswerving. It shows how strong and backed up the players are toward their gambling behavior. They are not ready to end it anytime soon. Initial thoughts on activities, affects the present and future of a person, including gamblers.
Those early thought don't get erased quickly or easily. Although, players have concern on making money, they still engage into gambling devotedly, even with no funds. So, I wouldn't call it a movement, but a problem. As the concept doesn't tally with the reason for gambling. Humans have redirected it and made the game a side hustle for wealth. Since it promises money, they'll never stop believing. In a nutshell, the validity of the believe is uncertain, due to the nature of gambling. Critically thinking on such beliefs can only take up time, with lesser results.
