Why are file views in SharePoint different from file views in GA4?

In the downloaded report from Site Usage, a document in the popular content is showing that is has 4 unique viewers and 13 visits in the last 7 days. However, when I hover over the file name in the Document library the file is showing 99 views and 42 viewers. Is this difference because the Document library is showing all views since it was uploaded?

When a report was created in Google Analytics 4 (GA4) to see the views and users, the file had 283 views and 250 total users. The report was also showing different languages (see screenshot below). This PDF was not translated and is only in English, so I'm not sure why it's showing different languages?
