Many people said the gambling is just a game and another people said it is Investment. How do you think?

For me it's a game, and others who said it's an investing, I don't think so because if this is an investing they save the money for nothing, because as far as I know, investing is saving to secure the future
Both of them has money involve but to compare the mission it just the same (they expect a profit)but the result is difference. I think more people are successfull in investing than gambling why? because even we always win in the end it turn to nothing while investing always positive result in the end.
