Mary is not a goddess, nor Queen of Heaven, yes.
But she is considered these things by some.
I refer you to another thread of Catholic apologia that inspired this post by me.
That thread, “Mary Matters” described her like this::
“her immaculate conception, perpetual virginity, assumption into heaven, her Queenship, and her role in Gods plan of salvation as Co-redemptrix
Those are properties of a goddess.

None of these are the properties of a goddess in the Christian context because none of it was granted her by or for her own merit. God alone granted and grants Mary her role in His plan of salvation.
