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.
As for me - you have some control only in sport betting or some card games. Only in the situation when your actions can change something. You can analyze the match or played cards and after it you can make your turn.
In all other casino games when you just drop your money and wait the result - you control nothing.
Control in sports betting is just based on your analysis, and so if you are wrong then definitely you lost that control. Or if the games suddenly chance, let's say one player got injured and so the outcome might change for the bad and you might lose it as well.
For some card games like Poker, maybe, but it will take years and years to perfect that craft. Those pro poker players didn't become overnight sensation. They really have to spend years behind to become so called a "expert" as they can read their opponents or pull off a great bluff.
