Yes, but “good at” here has a very limited, technical meaning, which can be oversimplified as “better than random chance.”

If something can be better than random chance in any arbitrary problem domain it was not trained on, that is AGI.

That raises the plausible question; are there problem domains where humans cannot do better than random chance, given repeated attempts?
