People always talk about new people. The way I dealt with it was just to tell them, "Hey, so I'm not so good at _________ yet. If you got a moment later, can you show me how you do it?"

I've said before that we aren't here to be BFF with our coworkers. If they're jerks, they're jerks. Don't stoop to their level and talk about them behind their backs. Hold your head up and do your work.
And know that we're always learning no matter where we are.
