People will continue to play at the casino in all cases. How much money do people lose at the casino, but they don't stop and keep playing at the casino. After all, people believe that if you play for a long time, you can eventually win and this win attracts a lot of people.
Do you know why they don't stop playing casino even when they lose? Because they want to get back their lost funds anyhow. Even though they lost more, when they win sometimes their hope becomes stronger. It doesn't make sense that gamblers lose every day and continue to play. Definitely they will win sometimes; that leads them to continue playing with hope. That's actually how gamblers become addicted.
On the other hand, if you win a big amount, then it does make you greedy. So to win more, gamblers continue to play more. It's true; if you win a big amount and share with others, they might be interested in gambling. That's actually how new people are inspired to gamble. Slowly they become addicted to that; either they are winners or losers on average.
Maybe I'll just add that when a gambler experiences a win, it boosts their confidence and they might think they can get something even bigger than what they've already won.
But they don't realize they're already under the control of their greed.
That feeling of contentment is gone, replaced by greed for money. Most gamblers go through this, but those who can control themselves will,
of course, overcome this feeling.
