Just WHERE do you find NewPipe described as a proxy service provider?
Their own description is as a local client that scrapes the web pages
and parses elements out of them. There is no description of a proxy.

"NewPipe only parses the YouTube website in order to gain the
information it needs."

From their description, NewPipe is no different than any other
webcentric client, like a lightweight web browser, but has a special
purpose of parsing the web pages it retrieves from Youtube (rather than
use Google's API - which does NOT mandate tracking or even logging in).
The author has yet to qualify why using the YouTube API is more evil
than his app parsing Youtube's pages (which is unreliable and will fail
when Google changes elements in their pages or the nav between them).

Screen scrapers or web page parses are unreliable. This isn't the first
author that tried this very old scheme (which was primarily used when
the service provide an API or target program did not provide a CLI).
Operation is dependent on the site not changes the critical content of
the documents (web pages) that it delivers. Yeah, like that never
happens at any Google site, uh huh.

NewPipe is just a webcentric frontend app. It is NOT a proxy service.
In fact, only the element parsing of the web page delivered by Youtube
is unique to this app. All thei video functions are borrowed from other
open source projects. It is a *player* that uses document parsing
(rather than use the Youtube API).

"without annoying ads"

Never seen any (of THOSE type of "page ads" which are NOT within the
video stream). I use a web browser (Firefox) to visit Youtube. uBlock
Origin is used in Firefox (on my Android phone and in both Firefox and
Google Chrome on my desktop PC) to get rid of page ad content not just
at YouTube but elsewhere, too. Inline/instream ads (part of the video
stream) will NOT be eliminated by NewPipe or any adblocker in a web
browser nor by NewPipe that is merely displaying the video stream that
Youtube found for that client's request.

Where do *you* see that NewPipe is operating a proxy server?
