This is true, a finch type bird would need grit as it does not hull. Budgies may eat grit for fun, not a good thing as grit can cause crop injuries in budgies since they are not designed to eat grit. Birds sometimes do eat non food items when they are short of something in their bodies. Macaws eat clay for this reason.
Budgies should be provided with cuttlefish and or mineral block. They are primary seed eaters, which is limited to a small range of commercially available seeds.
