Indeed, you were just right but there are some people or let say gambling enthusiast that they don't after the money had to lose as long as they are just satisfied and entertained will. For me on my own, I gamble because I enjoy it no matter how much the cost was being lost. Always having a good mindset is the best way to gain money.
It seems to be that there is a good reason why people keep gambling even for how many times they've lose. It is something to think that we can't be at the top without any struggles and being in a positive mindset will help it out to be good and give satisfaction.
