It is, in fact, categorically wrong, and misleads beginners to make bad decisions. Robinhood is notably bad for promoting this kind of gambling behavior on its platforms; they also state the same misinformation (that you buy a call if you think something is going to go up, when it is in fact a bet that it is going to go up more than a certain amount in a certain period of time).

People shoot themselves in the foot because they think NVDA is going to go up after earnings, buy call options, and then even though the stock goes up they lose money because they did not understand IV crush.

People looking for one-sentence explanations should really not be playing with options. In finance you should understand what you're buying thoroughly. If you just want to bet that "NVDA goes up", you should just buy NVDA stock; that is the trade that accurately captures that bet.
