Yes, baptists believe in the virgin birth of Jesus through Mary. However, while she is a prominent figure in Christianity, we do not consider her to have Devinne power or the ability to answer prayer.
In the Catholic tradition, Mary is much more revered. Catholics pray to her, say the rosary, and consider her to almost have a Godly power. Baptists believe that you should pray to God and God alone. No one else has the ability to answer prayer but God. Any by God I mean the entire Trinity (Fatehr, Son, Holy Spirit).
I hope that clarifies for you.
