We actually gamble to win the fun part of it is what i don't accept, if only the poor can gamble with what they can afford to loss gambling addiction wouldn't have been a major problem some countries are facing now. When a gambler diny himself food and still take on debt just to gamble then it's no longer for fun but addicted in gambling which is the problem most society is currently facing, most gamblers don't even care if their family has eaten some sell properties just to gamble and people who mostly does this are those struggling to survive when you are not struggling to survive it means you are not and can comfortably gamble without the next person knowing because no property is been sold out in other to place a bet.
No doubt, most gamers infact majority of hammers gamble to win but some gamblers also gambles for fun, addiction is not only about the poor but rather it is for everyone regardless of our financial status, it seems you don't know that there are wealthy people that are into reckless gambling, every gamblers can resist the urge of getting addicted it is all about discipline which has to do with strict decisions, learning how to say no to greed, loss chasing, temporarily going on break especially when you keep losing, having a budget for gambling daily, weekly or monthly will also help a gambler not to gamble without going on break, the things you mentioned happens when gamblers thinks that they can actually build a career around gambling or lets say make it source of living, it is unfortunate that there are gamblers that think abstracts.
