Not talking at 17 months?

Baby girl is almost 17 months old and doesn’t really talk. She babbles constantly. She does say hi, and waves. She claps, blows kisses, and gives hugs when asked (majority of the time). Pediatrician said he isn’t worried, but I can’t help but wonder if she is going to be really behind. He said that based on all of her other milestones met, she doesn’t need early intervention and that she will probably start talking one day and just not stop lol. We read, play games, play outside, etc. daily.

Should I be worried?
