No it isn't. It's speaking of Eve. Jesus is her seed as well as Mary's. It's quite a stretch to say that this scripture is "Marys presence in the context."
In the context, it is Eve.
I under stand why the Catholic religion has to see Mary there, but it just isn't so.
It is a good idea to read the Holy Bible every once in a while.
I would suggest that you increase your frequency of Bible reading. And pray the Holy Spirit shows you what it means.
If you are using a Catholic version, compare to the Greek and Hebrew for clarification of scriptures that are difficult for you to understand correctly.
That is of course true but Jesus is uniquely one born of Mary Who uniquely defeated Satan, so it is the "seed" of Mary and not Eve that makes the reference to Jesus complete and precise. Otherwise Genesis 3:15 would be saying that every one shall crush the serpent because everyone is Eve's seed.
Read the scripture frequently and use your brain when doing so.
