Oh, yeah! This illusion of control has ruined many lives. Including mine. Many years ago, I thought that everyone around me was a fool and that I was the only one who knew what I was doing. That I could go to a casino and win a lot of money. That I would soon become rich, but it was not to be. After some time, gambling showed me the other side of the coin. It took all the money out of my pocket and also forced me to accumulate a huge amount of debt. How wrong I was then.
And people still tend to make such mistakes. It is difficult to even imagine the consequences when this happens to a person who thinks exactly the same way as he did in his time.
Well, people learn the hard way most of the time. That's why, if you tell someone who is into gambling that it's a bad thing and it can ruin their life if they don't stop on time. It is also going to make them broke in no time, they won't take your words seriously, and think that it might have happened to you. Still, it's not necessarily going to happen to them as well, but people don't understand that it basically does work the same way for the majority, and almost 99% of the gamblers tend to be at a loss at some point if they keep gambling for the long term.
I have relatives who were too much into gambling, even though they have now stopped gambling too much, but at that time, they were too stubborn that they wouldn't listen to anyone saying anything, and their only mindset was that they can make a lot of money from gambling if they have a large bankroll because they know how they should bet if they have a good back up. We used to tell them it doesn't work, and you are eventually going to lose, but they never listened until they had some big losses, and that was the lesson for them.
