The Koran doesn’t present anything about Mary as Christians understand her. The Koran tries to say that Mary is considered by Christians to be the third person of the Trinity. This was based on the historical accident that the only Christians with whom Mohammed had contact were Nestorians, who have a defective understanding of Christian theology. But no Christians, not even Nestorians, but all the rest, Orthodox, Protestant or Catholic, have ever considered Mary to be a member of the Trinity. All Christians know that Mary is not God. They give the saints doulia, veneration, the Holy Theotokos (the God Bearer) hyper-doulia, extreme veneration, but to God alone do they render latria, the adoration due to God alone.
No. all christians do not venerate saints and worship Mary (your actions are worship no matter how much you play word games with hyper doulia). That is a Roman catholic thing not a christian thing .
Notice that there is no “Let it be done to me according to Your will” allowed to Mary; the Virgin Birth was “already decreed.”
