Should I be worried?

I’m kind of new to this subreddit and I gave myself an opportunity to scam a scammer back and I actually succeeded, but the only problem is that they have my number and they can have the opportunity to text me. Now the way that “she” said “I’ll make you surfer” is kind of worrying me a little bit and I don’t know if she actually means it or not. I’m kind of freaked out. And I’ve seen at least seen 13-17 year olds do it and have fun. But I’m kind of worried about the outcome for me though. (I’m 15 years old with somewhat high anxiety). I just need some clarity if they’re actually bluffing instead to strike fear.
