Gandalf was a Maiar, a severent to the gods, he's similar to the Valar, the beings who made the world, just lesser in stature, he's basically a demi-god. Sauron's protection isn't the same as giving immortallity, it keeps the Witch-king from being harmed in any way, his ring is was gave him immortality, the later protection keep him from being harmed.
