I think that there is some nuance: Day trading and short term plays are a casino. It is a zero sum game where every winner has a loser. Long term holds, index investing, etc. Is arguably not a casino since there is very much a way to play that is not zero sum. You are counting on dividends, actual value being created, and it is possible to make money without there being a 'loser'.
