I think you or we cannot rule out the fact that actually happens in gambling where most people or gamblers make gambling a place to earn, or simply they always prioritize winning in every bet, I understand that whoever it is that even though they come just for entertainment but still they will never refuse the name of victory but maybe the difference is that there are some gamblers who are too pushy to win and there are also those who wait with patience and maybe you also already know the two types of gamblers that I mentioned.
The gambler who want to earn money from the gambling site,need to increase their skill in the gambling site.The winning money in the gambling site can be increased based on their ability to make money from the same gambling site.The gambler with huge money mostly consider the gambling as the entertainment,because they doesn’t need any money to make them rich.Because they are rich already,this was the reason the rich gamblers easily increased their skill in the gambling site using their money to gambling site.The gamblers who want to multiple the money mostly take the big risk will leads to the big loss.
but do remember, if you are into luck-based games, don't ever expect that you will be on the winning side after you call it a day. even if you have tons of money and you are playing dice or roulette or any other casino classics, you won't go home as a sure winner.
