What is hamlet' concluding thought after he has mused over the skulls and the idea of death?

The Gravediggers relate to time as the ultimate equivocator. Time humbles all men because they end up in the same place. The gravediggers say that whether one is a king or a beggar they end up in the dirt. Time even things out. If you fallow their food chain logic a king sooner or later may go through the digestive system of a beggar. (Worm eats dead king- fish eats worm-beggar catches fish....) Hamlet extends this idea to how great men return to the earth just like beggars and ordinary men. Even Alexander the great is used to "to stop a beer barrel". This is everybody's destiny. No man no matter how great escapes the ultimate reckoning. This is a destiny our physical bodies all share regardless of God or the afterlife.
