Are airdrops worth the time? Can it even make money?

Lately, I've been researching crypto airdrops, and found it quite interesting but I am very skeptical (giving out money for free is always suspicious).

Can it be profitable? Or do you spend more on swap fees, and have to have huge amounts of money to break even?

When researching, I have mostly found very varied responses where someone could get thousands in drops, while others got cents. And it also apparently takes a lot of time.

I am not asking for specific projects. I would like to hear your experiences with them. Thanks.
