Did she offer me insult??

We have hired a new girl at my job and yesterday I did a little but of training with her. She was worried about handling money because she never has before and says she isn't great at math. My manager looked at her and said if "A" can do it then so can you. We have other people working here and I'm the only one she says if she can do it than so can you? It made me feel like she was calling stupid. Do you think she was meaning it that way??
