I think majority of people who are addicted to gambling is because they do not understand gambling as beginners, the rules and the side effects of playing gambling excessively.
I believe it is not knowing about gambling that lead a person to gambling addiction. It is more on the lack of self-control that lead a gambler to addiction. Looking at the definition of gambling addiction, we can say that the key factor is the uncontrolled urge to gamble.
In order to avoid gambling addiction one must nullify the uncontrolled urge to gamble and the key element is self-discipline.
I believe knowledge about gambling does not help in controlling addiction but rather helps in creating strategies to enhance the chance of winning. Several people who are knowledgeable about gambling still fail to control themselves and got addicted to gambling.
I think if gambling companies can help to giving beginners to understand gambling and addiction it will help and reduce the rate at which people get addicted o gambling, I mean good lesson for people to get understanding. Or do gambling companies benefit from gamblers who are addicted, which the awareness of getting addicted can affect their business?.
Casinos gives information about gambling and have a specific page for the information about how to gambling responsibly. They even have self-exclusion program where player can approach them to self-exclude and unable to access the gambling site. It is that the player failed to read the responsible gambling guide and most of the people who are into gambling often ignore the self-exclusion service of the casino.
Being addicted depends on the person himself. It is about his control over his gambling engagement. Gambling companies do benefit from peoples gambling engagement but they should not be blamed if the person get addicted because the addiction itself is created when the person failed to moderate his gambling activities.
