A deck has to be sent to people who should read it rather than edit it, and whose machines will not have the fonts.
Each slide becomes a fixed page with the fonts embedded, so the deck looks the same on every device. Text stays selectable and hyperlinks keep working.
Animations and transitions collapse to their final state, so a slide built to reveal five bullets one at a time prints with all five visible at once. Builds designed to hide the punchline until the end give it away in the PDF.
Not by default. The notes pages are a separate export layout and have to be asked for explicitly.
It becomes a still frame, usually the poster image. PDF cannot play it.
