I'm a bit torn to be honest. I think some of these people are just hustling, scouring the internet for opportunity.... which, in a backward way, I kind of respect.
But you're right, nothing that's actually worth doing happens overnight. Building skills is the true path to success and long term happiness. Which takes thousands and thousands of hours, and it's not easy. Not by a long shot.
Anything get rich quick should be a red flag.
