Does fullness of God suggest being God?

This is one of the circumstantial proofs used by Christ-is-God proponents. Accordingly, in Christ dwelleth all the fullness of the Godhead bodily (Col 2:9). So their conclusion is: Christ is God.
But in Ephesian 3:19, it says that even to people of God, the fullness of God is expected to be filled also as written, “And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fullness of God.”

It therefore follows that from above reasoning all people of God are Gods also.

Definitely absurd!
