Launch vehicles tend to scale payload capacity at a greater rate than dry mass. So a small launch vehicle like RocketLab's Electron might have a wet mass of 12,000kg at launch and an LEO payload capacity of 225kg (225/12000 ~ 1.8% payload), the SpaceX Falcon9 has a wet mass of 550,000kg and an LEO payload capacity of 22,800kg (22800/550000 ~ 4.1% payload).

This just tends to mean that, very generally and with exceptions, larger vehicles can get mass into space with less fuel.
