The way gambling addiction happens to one Mr A it's not the way it will happen to one Mr B, because I know that in gambling someone most develope much feelings that will make the person to be gambling addict, secondly, someone maybe chasing loses in the gambling and lure the person to be gambling addict, they are many factors that can leads to gambling addict, that is why I said that we have different things that can make someone to be addicted in the gambling, from my views, I think so many persons who is gambling addict today, doesn't know that they are addicted in the gambling except someone close to them informed, so as I said before that many things can contribute for someone to be addicted in the gambling, even when you feel that is only way of surviving, that can also lead someone to be gambling addict.
You have told so well, but there are multiple ways/reasons which may involved a user into gambling but ultimately the final step is to be addicted on gambling. Until any person is addicted on gambling I think there is nothing to be worried about whether the person is in loss or in profit. But when the person is addicted we have to worried about that person as the person can do anything for the addiction.
