Yes, there could be some gamblers who are losing huge amount of money and might not be a gambling addict. However, as a human nature, you wanted to get back with the money that you lost, so you want to play again and again and that could mean that you are turning into addicts.
But I do believed that there are addicts that can turn their life around. Maybe there could be addicts, but sooner or later they could be events in their life that they might realized that gambling is not for them and they are losing every grip of their live. So they could go into rehab, seek medical or professional help, or just shutdown gambling for good.
Chasing losses has always been the problem of many gamblers, and it's likely to lead them to addiction, but in rare cases though, some just chase until they realize that it's impossible to recover the losses and then they give up and maybe take a break from gambling for a while, while they reflect on their action and the losses they've made. Some people even decide to eventually quite on the process due to the huge amount they've lost trying to gain, they realize at that instant that if the continue with that gambling pattern, they'll only ruin their lives on the process so the best option is to call it a quit.
Yeah, most gamblers doesn't like to accept defeat and know that they are going too extreme like if someone is recording losses conspicuously why not give it a break at that material time instead of continuously playing and losing more money in the process and these has really been a big problem to many gamblers, for example someone will walk up to a gambling hall with like $200 and loses like $100 instead of him to leave with the remaining balance in his hand he will want to get back that $100 that he has lost already and by so doing they end up spending all the money in their hand.
Gambling isn't that too bad it's just the nature with which some persons play gamble that makes it look bad and as an irresponsible game. Like if you're playing and losing why not quite it like maybe for that day and continue some other time but some gamblers will keep on playing till their pocket becomes empty which is a very bad habit.
