For 30 thousand dollars you could go to Paris for a week and vacation there and come back while visiting great restaurants and historical things, for 300 dollars you could have a decent weekend at wherever you are, so it is not "tiny amount for a rich person" when it gets bigger since if you are super rich there is still other stuff you could do with that money, which is why winning is still quite important.
Very true. Some people think that rich people are not blown away by amounts like $30K which is true in some cases, but this applies to the minority based on what I have observed. Majority of the them still go crazy when they win such amounts.Majority of them earned money through their own hard work which is why they tend to value every single cent(Eg: Bill Gates), but a minority of them treat such amounts like nothing(Eg: Rich kids who never earned anything).
