Anything less than the whole is a subset, yes.

Evidence that any significant percentage of people, never mind the majority, is getting scammed? Then how many of them via app installs?

And to be honest, the level of effort scammers are willing to go through is shocking

Is it? If you live in a country like India, then a single successful scam will be able to pay for years of living expenses

Something about the smartest bears vs the dumbest humans.
