That's incorrect. High Sierra supports both 32 & 64 bit apps.

As Microsoft no longer supports any MS Office solution for the Mac other than the current Microsoft365 or Office 2019 for Mac, requires (presently) macOS 10.14.* (Mojave) or later for those installations, and they have disabled the license servers for older (e.g. Office 2011 for Mac) products — there is no Microsoft solution for macOS 10.13.6.

There is the free LibreOffice Suite (7.1.5), which is a superset clone of MS Office, or the paid SoftMaker Office 2021 for Mac (10.12+).
