That's not necessarily true, engines also create overhead. If you create your own engine, you can tailor it exactly to your use case.
Besides not all games need performance, I have been working on a clone of the original elite game using SDL. It gets 6000 fps easily.
The big difference is that the big game engines have to cover all sorts of genres and scenarios, which often results in bloated "jack of all trades master of none" code compared to engine-layer code that's highly specialized for exactly one, or few very similar games.
