Yes, there have been a few people who have become rich solely from casino winnings. However, it is important to remember that these cases are extremely rare. The odds of winning a large sum of money at a casino are very small, and most people who gamble will lose money in the long run.

However, a few individuals are able to defeat the odds by using systematic apps and algorithms. These individuals may make a fortune on betting but even so, they rarely become millionaires through betting alone. Betting is not a form of investment and odds are always against the individual who engages in betting.
