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.
You can see the illusion of control take over when some gambler is on a "lucky streak", which convinces him to keep gambling, as if there was some mysterious power out there that would ensure he would keep winning for a limited amount of time.
Add that to the superstitions that some people have, and the illusion only grows stronger and more in control of that person.
It is important to stay grounded, especially during high emotional events like gambling.
