1. If you have a lot of money, go gambling to reduce them.
2. And if you have too little money, go gambling to increase them.
But gambling is not something that will make increase your money or decrease money. It could be the opposite. Suppose you were gambling to reduce your extra money but you won the gamble and your money is increased. Think again you have very little money. You try to gamble to increase them, but you lose gambling and lose all your money.
So anything can happen in gambling. So should not go gambling with any hope.
I did not catch what you mean, This is the basic of gambling between winning and losing, and the most logical reason for gambling is money. but not the best way to spend money, I don't know if someone has too much money and throws it away at gambling like in poker, maybe that is a bit of entertainment, because games with strategy are sometimes fun.
