The working distinction: initial kull can distribute negation to every member; later kull can make universality the thing denied. But rhetorical analysis also asks why the speaker chose that arrangement.
If the addressee believes the whole group arrived, a sentence corresponding to ‘not all the people arrived’ can correct that assumption. If it is important to state that no one arrived, the universally distributed negative is appropriate.
The scope of negation and the requirements of the communicative situation are separate but closely related questions.
