Most addicted gamblers do not agree that they are addicted, which is a big reason why they keep failing and never rise.
Additionally only a few gamblers amongst the multitudes of gamblers gambles for entertainment as it's initial goal but so many gamblers are here for the money which is enough reason to keep losing more money because you can not put you hope to succeed in life with gambling.
That's a worse state of gambling addiction, when the gambler can not again realized that they are addicted even when being told. Although, addicted gamblers also fall in the advantage of making profit from their bets because they don't usually lose all their bets but they don't make good use of their winning but will rather spend it all on gambling. Take for example, if an addicted gambler is always gambling all the time and wins $1000, because of greed (and addiction) to multiply the money to $10, 000 he or she will continue gambling until they end up losing all the money. It continues like that for a life time unless the person later realises their self.
Yeah, I usually say that there's not gambler that doesn't enjoy the winning that comes from gambling but not all of them makes it a priority to win. Only a limited number of gambler have that desire to catch fun and leave without worrying over profit making.
