This last part of the Hail Mary prayer has three unbiblical parts to it. First, Mary is not and never was “holy.” Mary was a human being who was born, as all humans are, with a sin nature and who recognized that she needed a Savior.
The second unbiblical part of the Hail Mary is addressing Mary as the “Mother of God.” Mary was the human mother of the human Jesus Christ, who was indeed God incarnate. But she was not the mother of God, neither is she the ”queen of heaven,” another title given to her by the Catholic Church which has no basis in Scripture. God doesn’t have a mother, nor does He have a queen. He is an eternal, infinite Being, uncreated and unborn, self-sufficient and self-sustaining.
The third unbiblical statement in the Hail Mary is the plea for her to “pray for us sinners.” Here we see the unbiblical practice of praying to Mary to intercede with God for us.

Your source, https://www.gotquestions.org/Hail-Mary.html , is not “Roman Catholic”.
Ergo it’s worthless.
