The big gamblers do it for the thrill not to win some extra money. Big gamblers are already millionaire due their business, they just wan tto have some fun. For them to lose 1000 dollars is like for us to lose 1 cent, it means nothing.
But keep on losing 1000 dollars would be a big problem even for the big gamblers. So, gambling problems would be same regardless of your wealth. Only the time may differ to affect.
But you will not lose all bet that you make though because it will be always up and down so if you can have enough bankroll I think it would be in no time for your recovery. It is just matter of time and yourselves too how long can you control yourselves for being not busted too much
