That is very true. But she praised Mary nonetheless. That is exactly what a prayer to Mary is: it is seeking the company of Mary because Jesus is with her, and asking for her prayers to Jesus.

The Lord is with thee
Blessed art thou among women
And blessed is the Fruit of thy womb, Jesus
Holy Mary, mother of God, pray for us sinners now and in the hour of our death

As you see, Jesus in in the center of the prayer.
