Hehe.. they are interesting questions, but you may be overthinking it.
It's just something you're trying to develop within yourself. If your punch isn't quite right, they're not going to expel you hey

It's not a condition of entry, but something you develop there that actually HELPS you learn.
Another of the dojo kun is "We will train our hearts and bodies for a firm unshaking spirit." They won't reject you because you show weakness. It's a work in progress sorta thing.
But even so, humility is sort of a condition to learning anyway, so if you go into the dojo all arrogant, dismissing everything your instructor says, puffing up your chest as if you know better, refusing to listen etc, it probably: a) won't be a good fit, OR b) be a great fit if you're truly willing to work through that.
