Jesus is quoting the psalm which calls those in the psalm "gods" but goes on to say they are not gods just men. Jesus isn't telling His audience they are gods. If you think you are a god then you fall under God's curse:
“Tell them this: ‘These gods, who did not make the heavens and the earth, will perish from the earth and from under the heavens.’ ”
Jeremiah 10:11 NIV

Yes, Jesus is telling us that we are gods. The way He put it, "I said, ye are gods", regardless of the fact that we are all going to die, we are what Jesus said we are.
We are not only made in His image, after His likeness, but we are sons and daughters of the Most High God.
Like Jesus, we have authority over demons, in His name, by His word.
Like God, we can send His word, which is the power of God, to heal, if we have faith, or to cast out, and it is the word we send itself that does the work.
Like God, death and life is in the power of our tongue.
But God is the one who creates the fruit of our lips.
We are just too ignorant of Christ to walk in the fullness of the new covenant He provided for us.
