1. Even Leo Messi isn't "1000x more productive/as talented as the average [footballer]". Messi is a difference maker to be sure, and one might even say he counts for two or three men on the pitch, but even an extreme outlier like him only, perhaps, double or triples the statistics of another very good player. 1000x? No, simply no.
2. All of the recent studies coming out demonstrating that highly paid CEOs have no correlation with high performance, or worse either a correlation or possible contributor to poor performance, would say differently.
3. While most CEOs are certainly talented, many simply achieve their position thanks to connections and networking, and are not necessarily superhumans compared to their employees.
So no, this really says nothing about pay equality.
