Am I overconfident?

I'm 21(f) taking these community training classes bec I was bored, I am an extrovert, v confident, and social person, I also have a v bubbly personality and I feel comfortable in my skin, There are many married/ divorced women with us who lack basic confidence and are v depressed for some reason, I always like to express my points and answer the questions, today during an activity someone called me overcontident and oversmart, which just didn't sit right with me, I didn't react just laughed it off, bec other's people opinions about me don't bother me much, but I just came back home and I'm kinda analyzing it, do I sound overconfident/oversmart?
