This is a huge success, although I doubt that the player came to this purposefully. I also doubt that man will be able to repeat this success. His best bet would be to stop playing after this win or switch to a more conservative strategy. But we understand that this will not happen. Does anyone believe that the person will be able to keep this winnings? Most likely, this player will continue to bet on games with high odds and low chances of winning and will lose that money. This is a common story that happens to players. In the short term, many of us will have winnings, this is normal. But the paradox is that it is short-term gains that can lead to long-term loss of most of your capital.
you have a point here, winning a huge amount is indeed a very lucky reward and it's rarely to happen, sometimes when you win big, it doesn't come anymore, it's like beginners luck so it's up to you how to manage your winnings.
Winning big but that will not make you come back gambling anymore then I guess that's the key to be rich or successful in gambling. However, you only called that luck and much better if you get lucky on lottery or parlay with huge payouts so you'll be satisfied with what you win. Even if sometimes we win big but we aren't satisfied still, we will still lose because they (casino) have the edge and we all lose in the long run.
If you're smart enough, you'll become rich, but if you want to continue gambling, possible that the money you've won will run out little by little.
it's another thing, if we talk about being "smart" in gambling, that means you don't focus on games that you not skilled based, being smart is making your skills work for you until you become consistently winning in gambling which I think only few can.
