Ammo efficiency is how many ammo are required to deal sufficient damage. It is highly tied to damage per ammo used.

High rof, low damage = very low ammo efficiency <=> low rof, high damage = very high ammo efficiency.

To a lesser extent, rate of fire is also a factor because lower rate of fire means you waste less ammo due to recoil or continue shooting after the target is dead. But it is still something to consider when comparing ammo efficiency.
