It's just another phenomenon that gamblers often assumes that they have some control over the outcome of their bets especially if they have been doing it for a while even though every time is just purely random there's no skill involved. Take dice for an example we might assume that we can control and influence the result of it by throwing softer or harder or in anyway that our brain recognize a pattern and keep tells us it's a way to win the game. So let's discuss about it.
What you say is true, because basically the game situation actually changes what we think, although when we actually have limits in gambling but often those limits are destroyed just because of our greed, as is the case with the illusion you said, many of gamblers believe that they can influence the outcome of the game in certain ways, such as choosing a slot machine, the technique of rolling the dice and even the pattern of the picture on a particular game, but In reality, most gambling games are based on luck and chance that we cannot guess at all, because there is indeed no skill that can change the Outcome of a completely random game like slots, dice or roulette.
