You are right, its location-based and situation-dependent. I can be happy with winning $100 because a regular worker here in my location will not earn that amount in a day, not even a bank manager, but for those addicted to gambling regardless of their location and situation, they will always aim for a bigger pot; they will never be satisfied with 3-digit winnings; they want something to brag about to their peers that satisfies their ego.
I agree with that, But I wasn't talking about addicted people. I know they won't be satisfied with a three-digit win; they will always look for big wins. I was talking about wealthy people or high rollers who usually look for big wins as their bankroll is big, and they place big bets as well. If someone makes a few thousand dollars per month, I am sure they won't be too excited after winning $400. This should apply everywhere in the world. But if I make $400 a month, regardless of where I am from, I will be too excited with such a win.
Usually the richer or wealthier a person is, the more meaningless the lower denomination of money mean to them, so let's say a person is making like $20,000 or more guaranteed money every month, $400 may mean still mean something or absolutely nothing to the person depending on the type of person he or she is and how much he or she have struggled before he or she became rich.
For example, if myself become a dollar millionaire or billionaire, trust and believe me when I tell you that $400 dollar will still mean a lot to me because I've suffered and have known how hard it is to become wealthy.
And the same also applies to big wins as well, for some high rollers, a $400 dollar is a big win, while for others, a $400 win may be to them like they won $4, all depends on the person, their level of wealth and how much they value money.
