does using drywall anchors hold more weight than using plain screws?

If yes… how??

I’m currently in the process of hanging some furniture onto drywalls and was wondering about the claims on dry wall anchors to hold so-and-so amount of weight. Could someone explain to me the physics behind these things? I don’t get how dry wall anchors can claim this.

Doesn’t gravity and the quality/sturdiness of the wall and the thickness of the walls be what determines the weight capacity hanging on a point in the wall? How does putting a drywall anchor help other than preventing direct contact of the screw with the wall? I understand you would like to protect the hole in the wall from the sharp edges of a screw but do drywall anchors also ease the load off of whatever is hanging on it?

Tldr; would like to know the physics behind how drywall anchors.
