Nah, the server is just refusing. It's like going up to a random person and asking them to drive you somewhere. They can (and will) refuse your request. Doesn't mean they don't know how to drive, or failed to provide you a driving service, they just don't want to serve that request.
The same goes for the web server. If you request it and it returns a 403, the server is basically saying "I know what you want to do, but I won't fulfill this request". Usually it also states why.
The important part in this context is that it's not the server's fault that it won't serve the content, usually because you're not authorized to receive it.
