Christ defeated Satan his mom didn’t.

Of course. However, she received the grace to cooperate perfectly with His Holy Will in the mystery of redemption.

"Hail, Mary Mother of God, venerable treasure of the whole world . . . it is you through whom the Holy Trinity is glorified and adored . . . through whom the tempter, the devil is cast down from heaven, through whom the fallen creature is raised up to heaven, through whom all creation, once imprisoned by idolatry, has reached knowledge of the truth, through whom nations are brought to repentance". (qtd. in Luigi Gambero, Mary and the Fathers of the Church: The Blessed Virgin Mary in Patristic Thought) - Cyril of Alexandria

it is you through whom the Holy Trinity is glorified and adored . . . through whom the tempter, the devil is cast down from heaven, through whom the fallen creature is raised up to heaven, through whom all creation, once imprisoned by idolatry, has reached knowledge of the truth, through whom nations are brought to repentance"

No, it is through Christ that these things have been accomplished. Give the glory laud and honor to the Creator, not one of His creatures.
