Archangels are much stronger than normal Angels. When Cass said they were the piranha that'd eat the entire aquarium, he was referring to the Angels in the garrison.

Most angels live in heaven and are in their true forms which are energy entities the size of a skyscraper. Unless the leviathans are as big as angels and they can enter heaven, which I doubt, Death meant they would devour physical creatures around the known universe. on planets. Archangels live with God or at least right next to the proximity of him.

The 4 archangel brothers and Death the Horseman are the only ones who've seen God's true image. They converse and even have a relationship with him. It's perfectly logical and within reason that they should be older than Dick, Edger, and the rest of the leviathans.
