"Printing" to a PDF document from most apps will embed fonts in that PDF document, including MS Word. I'm surmising you're new to the Mac OS particulars such as the "Save as PDF…" command - I use it every day.
In most apps, the "Save as PDF…" Command (that's an ellipsis at the end) is embedded in the Print Dialog Box, in the PDF Pull Down Menu in the lower left of the Dialog Box - choose that Command and you'll be prompted for a file name and location to save it.
To verify for yourself that the fonts are embedded, you'll need another app. I use Adobe's Acrobat DC but their Reader app will suffice - you'll need to download and install it. The "Document Properties" Command in Reader will display as one of the Properties options any/all embedded fonts.
Regarding Word, I've used it since the late 1980s and it's an unbelievably powerful tool in the right hands. My gripe with MS is that the Mac version is gimped/hampered/fettered when compared to the Windows version. I use Word for Windows every day, and never use the Mac version as IMHO it's missing so many features including the option to embed fonts directly as the Win Word app allows; Apple bails out so many of us by embedding fonts in its version of a PDF-reading app that's more powerful than most give it credit for. I use Word when I have to - for my written work, I use Scrivener now - the Mac version, even though there's a Windows version available. Scrivener still uses the Mac font-embedding for PDFs, but the person on the other end of my workflow also has the fonts I use as well. This isn't a rant, you should be covered now. Cheers!
