I think it is similar for managers and developers. There are 10x managers and 10x developers, but both are very rare. The are also net-negative managers and net-negative developers, both are a minority but sufficiently large that most people already met a few of them. That is, a manager can "create more than any individual contributor", but most of them don't.
