Gambling is a kind of game that takes valuable things to bet on, and is a way of human entertainment. Any gambling has different meanings in different cultures and historical backgrounds. In western society, it has an economic definition, which refers to "bet money or something of material value to win more money and / or material value for an event and uncertain result".
Because gambling is for-profit, if you are lucky, you can take advantage of it and possess other people's wealth without any effort to realize their desire to become rich. Therefore, some people regard gambling as a ladder leading to wealth.
