I don't think so. There are a lot of people who are lucky enough in gambling wherein their life has been really changed because of gambling. At the end of the day, it's still depends on the luck of a person.
Yes, gambling can change a person's life for the better but that is only temporary, greed will be difficult to control if gamblers have considered gambling an easy way to get quick money, meaning too underestimated. But I believe there are still people out there who are able to live happily from gambling by managing profits and press losses well.
As the nature of gambling, everything revolves around luck. In order to be successful in life, one must posses the skill, intelligence, hard-work, and luck throughout the adventure. People who became successful due to gambling are also the ones who posses the said traits and it is only a matter of perspective on how one views their success. Regardless, everything has an exception and that may be the individuals who won the lottery or by even a one time all-in bet in gambling.
In gambling wins only those who organize it. A person who makes bets can win from time to time, but if you count the amount of losses and winnings for all the time, the calculations will not be in favor of the person.
Gambling should be considered only as entertainment and not to spend large sums of money, then everything will be fine with you.
Like any other hobby, they can be addictive when it gets out-of-control and if the person lacks the discipline. What makes gambling addicting is the result and satisfaction of earning large amounts of money relative to your money risked. Unlike conventional jobs, you get paid daily, weekly, or monthly but in gambling, you can achieve those in one night.
