There is no if X then Y. Some people will feel superior to others while some people might feel the need to hoard their money even more after a big win. Human beings are individuals and make their decisions in different ways and under different circumstances. But experience has a lot to do with the course of action they may take in the future. I have the feeling that especially older people who didn't have much when they were younger tend to hoard more than others. But if you are in your 20s to 30s, have never been poor nor rich, and out of a sudden you win this lottery jackpot, I think a lot of things can go wrong.
If there are people who feel superior to others, that is normal, but they need to know that each person definitely has their strengths and weaknesses. Humans will definitely act according to what they can and will not do something they cannot. If they gamble in their 20s and, win a lot of money and use that money well, they will probably retire at a young age because they have succeeded in having passive income. And when they grow old, they no longer worry about anything and enjoy life well. But if that person instead uses their winnings to try to get other winnings, they are greedy because they don't understand that they have already earned a lot of money and should be able to use it for their own good. They may no longer be able to get big wins like before, especially if they are too eager to gamble.
that players in poker went broke but some of them bounced back and are now back in business these days earning a lot of money. But the reason they are hiding is not that the players play so well and are professionals outplaying everyone, the reason is that most of these guys now have advertising contracts or are otherwise associated with platforms that guarantee them a certain income and probably participation fees in big tournaments. As you can see some of them would have gone broke if it wasn't for the Internet and social media to save their asses.
