I think that it comes more down to financial literacy and whether people understand accompanying costs that come with certain assets. For instance if someone wins a lot of money and buys houses and cars, that person might not have the understanding of those assets necessary to calculate long-term financial consequences and also short-term costs that could be inflicted for unexpected reasons or just reasons not known to the new owner. A lot of money needs a lot of planning if there is a lot of buying. If someone just leans back in their old apartment paying for the same stuff as before, life will be easy and wonderful. 
That means it depends on how someone can manage their finances well and correctly, especially if they can get big wins. It will require careful planning to carry out. Having a lot of money from big wins from gambling will make someone feel that they are superior to other people and they will start buying things that they don't really need. They can still live simply as before and the money from their big winnings can be saved for other things. They are better off using their winnings for long-term investments that can provide big profits rather than buying things they don't need. By investing, they can have a source of passive income to prepare for the future and they can still live a simple life and there will be no problems.
