I'm not entirely sure how to answer this question. There's very little concept of being bad or good "for your rating" online. You are probably just as good as every other player rated 545 rapid.
Now, if you're asking whether 545 is a good or bad rating ... I'd say it's bad. But that's okay! It looks like you started pretty recently and chess is a hard game. The hardest part is just being aware of immediate captures - take free pieces when you can, and avoid giving opponents free pieces. Also playing against humans will let you improve faster than playing against bots.
Good luck improving!
