What is this? I don't know if I find this question funny or straight weird.
Anyway, it seems you are simply overthinking here. There's madness/insanity everywhere, not just in sports betting or gambling. We are all insane and crazy in one way or another. We are all crazy and mad in another's eyes.
Everybody can predict, give their opinion, analyze, and so on. I mean every single person, may he/she be an expert or outright ignorant. The problem with underdeveloped countries is that there is poverty and ignorance and, of course, extreme laziness as well. People are so desperate to get out of their abject living condition in the easiest way possible that they would even try their luck on a deranged person.
I have seen this myself. A seemingly normal person asking for a lottery number combination from a mentally-ill person. My goodness! If this is the way people think to get out of poverty, I'm afraid they will remain there all their lives.
