Here is direct translation from Hebrew.

and enmity I put between thee and the woman, and between thy seed and her seed; he doth bruise thee -- the head, and thou dost bruise him -- the heel.'

Notice the second him? That is from a masculine only word.

Now for the first he.

הוּא is masculine and הִיא is feminine. Guess which one is used in Genesis 3:15? Yep!! ה֚וּא

Mary being feminine is not included.

I know that. The point was that the promise involves Mary in the context. Learn to read and comprehend the matter read.
