Yes, that is correct that God has no beginning or end; God is the I AM, Almighty, long before Mary was born, long before the universe was even created, yet God, the I AM, knew Mary before she was even knit in her mother’s womb and she was included in His plan to bring about salvation to all of us before the world was even created.
She is the vessel whose “yes” allowed God’s will to do His work among mortal men.
We have to remember that God is pure Spirit and He uses people, things and situations to speak to us and communicate with us.
If we can believe that God, who is pure spirit and who is all-knowing, all-infinite and all-powerful, could limit Himself and became a man in the womb of a young pios Hebrew girl, then why is it so hard to give Praise to God for giving us the perfect Mother?
Mary has many titles, including Mother of God, Blessed Mother, Blessed Virgin, Holy Mary, Queen of Heaven,; the link will bring you to a prayer that will list some more:

All prayer to Mary or really any Saint or any type of prayer devotion leads to JESUS, GOD, the ALMIGHTY.
If I bumped into you on the street, say you were a friend of mine, and I asked if you would pray for my sister who is struggling with addiction, and you said yes, and you did offer up prayer to God that He would heal my sister, well that is like how we pray to Mary, the Mother of God.
Hope this helped you in understanding.
Also, I am a visual person and I need things to remind me of God’s great love for me and not just words, and He knows this, because I tend to be a little forgetful and that is why God allows us to have statues because they remind us of Him.
