Sooner or later, they will addicted to gambling. Once that is happen, they will ruin everything they have and even their life.
Each gambling addicted is different. Being gambling addicted isnt something uncurbable and does not mean that everyone will ruin their lives with 100% probability. I think everyone who has tried gambling at least several times are already addicted, because they return to gambling anyway. We have different forms of addiction, someone return and gamble daily, someone on special occasions, someone gamble once each month. But that does not mean we all are moving towards ruining lives.
Right, there are people out there (specially those with a deep religious background) that believe being addicted to gambling is the same as gambling once a week or even once a month. In reality, addiction to gambling is not something which is definitive and will come to all of us as something which will have one hundred percent of chance to ruin our life.
The majority of us will lose some money, that is for sure, but we will retreat in time and call it a day before we even think of gambling with no ey we cannot afford to lose to our bad luck.
Comments like those only show who much stigma there is accumulated under the figure of gamblers and those who partake in any kind of activity which have anything to do with randomness.
