The rich folks usually have alot of money to risk, so what the poor might be calling their life savings may be spent in a single round of gambling section. These sets of people already knows the kind of risk that's involved in gambling and so they go into it with advanced risk strategies. They can just do an few rounds with huge risk and call it a day because they probably must have made enough. But for a poor or average folks, we want to keep trying out our luck, using very small amounts of risk.. it's not totally bad as it's a way to keep our mindset at ease. You shouldn't take risk you cannot afford. It's something every gambler should have at the back of their mind..
