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.
Illusion for me in this regards has more to do with players expectations, I can remember making those commands in dice game and most times it works perfectly well as assumed or expected, and this assumption or expectations is what shows how much of our interest in the game, surely there is no skill in that the reason why it doesn't work all the times irrespective of how much we attempt to control or maintain pattern we are comfortable with to achieve the desired result, trust me there is nothing of such as a gambler assuming to have a control over the outcomes of their games it works with luck.
