I guess this happens very rarely. That person was probably lucky, a real lucky one. But I think there are so few people who can win 30,000 euros from just three euros that the odds are probably one in several million. Well, this is already a success story, and it will inspire people who might want to play sometimes for a few dollars to win a big prize. And if you play a few days a week for 3 dollars, it doesn’t seem like that much.
If you learn something from your mistakes, you've won in life!
I know him personally, a great worker, he had debt problems for his former partner, he left the company and all the problems with the banks.
As a non-gambler (certainly also desperate for his situation) he tried, he still risked 3 euros, which for a person with debts is still extra money in something that trivially seems useless.
He maintained his coherence as a person with his head on his shoulders, he paid off all the debt and now starting from scratch he has built up a nice business! For me this is what happened! In gambling, however, it's just luck, which when it comes if you are a determined person and you take advantage of the opportunity, even a decent win changes your life.
