I’m not sure about others out there, but in all the parishes I’ve attended (5+) and in all my experiences with Catholics, the answer to is unequivocally “No, Catholics do not worship Mary.”
I would be highly concerned if there were any worship of Mary because I think that is or is very close to idolatry. But in all my experiences, including my own, the primary focus on Mary is one of reverence, not worship.
