Maybe it really depends on the demography once again when it comes to earning from playing games. I think I have tried very before like 2 years ago , and it was not that easy to earn there.
I have tried cointiply back in the year 2018 and it might be possible that they might have introduced more ways to earn money and also improved their earnings. There must be some truth behind the claims that people are indeed earning there, so I will provide my suggestions after I try their app soon.
