Jesus only cast demons out of people who called Him Lord and believed in Him as their Lord.
Jesus never cast demons out of people who did not call Him Lord except to free them from bondage so they could choose for or against Him (the Gadarene for example).
So Jesus believed it was necessary to follow Him as Lord before He delivered people.
They were Christians when He usually did it, so it shows Christians can have demons.
