Average means acquainting oneself with wrongness and adjusting with it in mind, rather than always (and rather unfairly) measuring ourselves against a checklist of everything going exactly right. Yes, it does very much mean that you are human, but also it begs that you understand the very crux of your humanity.
We tend to forget how human people really are when we come to admire their achievements. All those great icons of industry, philosophy, history? I think they were keenly average; intimately familiar with wrongness, making whatever went right for them *that* much more impactful.
Being above average would make the state of wrongness, therefore a lot of the human condition, very very painful. This is why many people cannot be the successes we desire to be — because we weren’t wired to be kind about failure, especially to ourselves.
