Just to clear something up, Titans, gods, and Primordials are all just titles. When Zeus waged war on the Titans, he called himself and his siblings the gods to differentiate between the Titans. Even some of the Titans took the name of the gods, like Aphrodite who could be considered a child of Ouranos. Basically, they are called gods because that is the name they picked for themselves.

Typhon however is called different things depending on the source. Most agree that Typhon was a large storm giant that was the last of the children Gaea and Tartarus had together. He was Gaea's last attempt to defeat the gods before she went to sleep. So he could be considered a close relative of the Gigantes, but a different kind of giant.
