As a christian, is having statues of saints and mary and pictures of the pope in your house idol worship? [Spirituality & Religion]

My mom has WAY too many of these things, she criticizes Hinduism a lot but is her talking about saints not the same thing? I tried to explain it to her in a calm matter but I don't think she wants to listen, what is your thought on this? Worshiping mary is worshipping an Idol, no? Since mary was like any of us and only Jesus was without sin.
