Are some comediennes like Amy Schumer and Tracy Elis Ross not funny because they use humor to cover their insecurities?

And nobody really wants to sit there and listen to someone talk about themselves for a whole hour even if its in a joking way. there's a diff between this and self depicting humor in my opinion. One is not that serious and the other, when you hear it, is like 'oh here this person goes again complaining about themselves'.
