one of the triggers of gambling addiction is the desire to chase losses, and then they got lost (addicted) along the process.
This is what makes many gamblers end up getting addicted because they want to recover their losses and keep trying. They never think about how much money they will use to chase losses and how much they are prepared to lose. Even though, in the end, their losses are getting bigger, they still don't stop, making them even more addicted to gambling, and it is very difficult to stop it.
