Not at all.
If Mary and the Saints heard and responded to all prayers, it would be only a fraction of what God knows and can do.
They would still not know the position of every subatomic particle in the universe, or the answer to so many questions, such as the day of final judgement, or how each soul would be judged, etc.
So my point stands.
But now you’ve got me curious as to what other abilities Rome wrongly attributes to Mary.
