A loss initially prompts a philosophical attitude towards gambling, but a win can cause an inadequate reaction.
Winning is a huge challenge for the psychological balance of the player. The player needs to prepare in advance to philosophically perceive winnings in gambling. He should not perceive winnings as his salary (which is known to be paid regularly).
Winning is random. Fate and chaos are very scary opponents for a careless player.
A person that stake with low amount of money and win thousands of dollars at once, is that dangerous? A person that gamble and lose, win, lose again does that means the person can not become addicted to gambling? No mater how someone is gambling, the person would win and lose, those are normal to happen.
Because someone lost a bet the first time does not mean he will not gamble again.
Nothing change the fact that it is loss that causes depression and the reason for someone not to get addicted because addiction will offer more loss.
