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.
Nobody can control the outcome of gambling unless they're manipulating it, gambling is supposed to be based basically on luck. Most casino games like slot and dice are based on luck, there's no special skills that is involved to play and win, so any feelings of being in control while playing can as well be seen as illusions. But skills can be involved in sports bet, if a bettor understands teams strengths and weaknesses, it can guide them to analyze matches. Being overconfident and having a feeling of being in total control during gambling can lead to chasing loses and degenerate to addiction.
