Money is relative to the wealth of the individual. For most, 1M USD is a lifetime of money, if not several lifetimes in some places. However, for the whales and the big players, 1M USD is just change. It is difficult to understand for people who will struggle all their lives to make a living for their families, but there are people out there that will loose that amount and will not even blink.
You're right, mate. Only rich people can afford to spend enormous amounts of money, even for a single use of their money, for example, shopping.
But for those who don't have much money, having 1M USD is still a dream and we will feel frustrated if we spend it only on gambling.
That kind of money can provide for our living needs for many years for people who live in countries where the cost of living is not high.
We can only learn from what others have obtained so that we can take what is good to apply to us and leave what is not good.
Same with you, that huge amount can be a fortune to someone who's living in a third word country, it can provide luxuries for a longer period especially if the person are capable of establishing a business that can really give them continuous sources of incomes, though, it's also true that there's people like the gambler who lose that huge amount who can let it go and continue playing.
in my country 1 million dollars can be enough to support me and my family for up to 10 years or more if you build a business at the same time, lol
but that's how rich people play when they want to get a little profit they dare to spend big capital and they don't think they will lose big money too in their bets
Like what I said, if the person who have that huge amount of money who's living in a place where cost of living is not that much, they can put up business and investment that can bring more income, in terms of gambler who can lose that amount, either a whale or an addicted gambler who can embrace that risk.
