This is correct, as there are a lot of people who have made a fortune from gambling, changed their lives with it, and have been doing well for life without falling victim to gambling addiction and losing it all. There are also those who made it from gambling and also ended up losing everything to the same system without saving anything from it. There is also a category of gamblers who have lost it all to gambling. Gambling should just be followed with sense; don't put in all your hope thinking you have perfected your skill.
Do you really think there are many players who managed to make a fortune from gambling and changed their lives for the better because of it? It seems to me that even those who manage to win like that will keep playing and eventually lose a significant part of their winnings, or even all of it. Besides, there are many players who continue to play at a loss and believe that one day luck will be on their side, but all that awaits them are only bigger losses.
