When you include a font in an EPUB, the whole font file (.ttf or .fot or whatever it is) is included in the collection of folders & html files that are zipped up into the EPUB.
EPUB is not so much a "format," as a way of packaging HTML files with a bit of metadata that says "this is an ePub file." You can include fonts in the package, but they're not embedded in the HTML files. Instead, the metadata says "use the font font at <location> when displaying these files."
By comparison, PDF embeds the font into the PDF--it's packed up into the file. (I'm told some coders can un-extract it, but it's not a simple matter of unzipping. And fonts in PDFs can be partially embedded--so only the characters actually used in that PDF are included.)
The big difference: Many fonts, including free fonts, are free for
use but not
distribution. Embedding it in a PDF file is "use." Putting it into the EPUB zip package is "distribution," and not legal to do without permission or payment.
Setting fonts of your choice for your own ePub reading is fine; setting them in an ePub to share may require permission.
