humility
I think binary opposition between humility and arrogance is incorrect.
Your ability plus external factors is the outcome.
I can observe the results, but not my ability.
If you blame external factors when results are poor and attribute them to your own abilities when results are good, you will overestimate your own abilities.
Response Bias Dunning-Kruger effect
Suppose we are comfortable with calling this arrogance.
Conflicting with this is blaming oneself when results are poor and blaming external factors when results are good.
It is not a virtue. It is a lack of self-abasement or self-assurance or some kind of psychosis.
We're in a situation where neither end of the dichotomy is good.
The right thing to do is moderation, to properly assess one's self.
False dichotomy
