I disagree with the statement, rich people do gamble most of the people in the casino is rich people that looking way to release stress and some even are addicted gambler, but lottery is not going to be played by the rich, because they don't find any excitement in lottery and the chances of winning is small, in the other hand the poor hoping that by buying lottery he can win it and out from poverty, the poor choose the lottery because its cheap and the prize is huge
It seems a lot of people just prefer reading the topic or taking a quick glance at the post and commenting without making an attempt to read the OP fully. Simply put, the OP only needed you to get the idea of how rich people perceive gambling which he mentioned the title an overstatement, not like he said, rich people do not gamble at all. Oh sorry, I forgot, you would not know since you did not read it.
Everything the OP has said is the truth. Rich people do not come to casinos to play game for the winnings, they do so to have some good fun in their own way. I cannot say if they do not end up playing game of chance or not though, but even if they do, they are not playing just to see how their luck can get them richer, but they do so just to while away some time, which is something the poor man can never do.
Take a look at the statistics of the poor men who gamble, they are doing it to see if they can get lucky to see how their life can turn around for good by becoming rich with their activities. You would not blame them, as that would generally be the common mindset of any poor man.
