If when you lose money you win money - gambling becomes dull like freerolls. It is still gambling but without risks.
But you`re right that with huge money your life would be another. You will think about lots of other things, gambling wouldn`t be the main part of your life.
This is true for us that still doesn’t experience the luxury living when we are rich. However, gambling is a source of entertainment which rich frequently use to have fun on things they have a lot which is money.
There’s a lot of high roller on casino while most of them are rich people enjoying gambling despite being rich and use money to enjoy their life.
We have different life choice tho.
I can suppose that part of these people visit casinos because they can talk with some other luxury people. Or there are some events they have to visit. It is another life with other rules and we can`t say how it is until we become rich enough.
Of course someone like the process of the game and they get emotions in casinos, but i`m sure that they don`t play online - they need show more than the game.
