A small percentage of gamblers do find success and manage to create a stable income through their efforts. For these individuals, their outcomes might be described as destiny rather than mere chance. Destiny, in this context, can be interpreted as the culmination of skill, experience, and sometimes, the right opportunities aligning at the right time. When factors like luck and destiny converge positively, it is indeed possible for someone to succeed against the odds.
I agree that there is a small percentage of gamblers who have found gambling as their stable source of income, they have successfully managed their strategy and grew with it. So I don't believe it was destiny for them, rather it was hard work. Hard work pays in all ramifications.
It is a result of experience and determination to succeed. Those few gamblers have overtime paid attention to little and big details through their gambling experience which includes both failures and success. Hence they came up with a workable strategy which they have adopted. For example, the few gamblers I know that have been successful in football betting are those who bet few games. These set of people avoid martingale kind of betting, they just bet on it and wait for the outcome before deciding on another game to bet. Also, they don't contemplate parlay or multiple betting. They just select few games and options like 2/4 games which could give like 3/4 odds and go on high stake on them and most times they have positive results. Personally, I realize also that betting on few games is a good strategy in football betting.
