The strategy outperforms all other strategies (of the player), not everybody else's.

How can everybody have a strategy that outperforms everybody else's strategy?

Consider the typical prisoner’s dilemma,

$$
\begin{array}{|c|c|c|}\hline
&{\rm confess}& {\rm lie} \\ \hline
{\rm confess} & \color{red}{-8},\color{blue}{-8} & \color{red}{0},\color{blue}{-10} \\ \hline
{\rm lie} & \color{red}{-10},\color{blue}{0} & \color{red}{-1},\color{blue}{-1} \\ \hline
\end{array}
$$

In this case it is easy to predict that each player should play confess, regardless of the the selection made by the other player. Or in the words of the problem:

> The best strategy (the one that outperforms other strategies) is to confess regardless of the strategy adopted by other players
