I'd say that all depends on what sort of ambition you're talking about. If it's the sort of quiet ambition of self-improvement, then no; if it's the sort of ambition that requires winning out over others, then yes, that is some brand of incompetence - probably one of spirit more than anything else.

Of course, there are people who will tell you that ambition is merely situation wherein one hasn't enough sense to be lazy.
