These stats are updated monthly, and based on millions of loads of each site. The WhoTracks.Me page for wikipedia.org (https://whotracks.me/websites/wikipedia.org.html) shows that the Google Fonts and Google Static trackers occur very infrequently (<2% of pages), so may be on some part of the site that you did not visit.
While the Wikimedia tracker may seem innocuous, they do set a cookie that is sent in third-party contexts, and have presence across several sites beyond Wikipedia (133 of the top 10k) (https://whotracks.me/trackers/wikimedia.org.html). Theoretically, they could track user sessions across these sites. In reality this is likely an oversight in the server configuration, but objectively this profile looks no different to that of a legitimate tracker.
