If You Could Lose, Why Would You Risk It?
Gambling is actually one of the option out there if you're looking for ways to entertain yourself (of course, only for people who can control themselves). The different emotions you would feel plus the possibility to get something from it (through winning) is certainly satisfying. This is the reason why despite of the inevitable losses that a gambler can face, the satisfaction is what matters for them.
However it's a different thing if we're pertaining to an addicted gambler since they are uncontrollable, just playing blindly either to win huge or get back what they already lost.
And it is impossible to get back what he lost. And I think that even gambling addicts know very well that they have lost their money in the game forever. But some inner feeling, maybe resentment or hope to win and recoup still makes such a player continue to play. And accordingly, he continues to spend even more money.
I fault your point a little, just a part.
Well, for me, the losses do not mean you can never regain them back, the only cautious part is that you should not think of it as something you can get by all means. That desperation is what puts gamblers into more trouble and I've never read in the history of risky activities that the desperate people who are trying to revenge their losses eventually win, at least, more than 99.50% will continue to lose more.
