No, you read too much fiction.
Real people aren't stupid enough to fall for whatever shit as long as someone "talks well" unless they are mentally burdened in some other way, like most people that need help of those two professions usually are.
These "Kids" (legally they should be adults right?) might be immature but thats it, their biggest trouble seems to be "love", an issue far removed from the base needs that would put a human in serious mental distress, which is basically a requirement for "talk no jutsu" to be especially effective outside situations of group pressure.
But hey, maybe I'm just overestimating humanity, it is overall quite the disappointing race.
