Probably not. XSS is only possible when the browser interpret the response from the server as HTML. This is triggered by the following response header:
In your case, it seems that the browser interprets the response as text, as indicated by this header:
In that case, the browser does not interpret HTML and tags will show up as tags.
I base this conclusion on the font of your screenshot. Of course it could also be a HTML page with a particular font.
Sometimes it is still possible to trick the browser into rendering HTML, even when the content-type says otherwise. This is because browsers sometimes do MIME-type sniffing: they try to guess the content type of the page.
