Do all fedex packages have tracking?

I ask because I recently needed a new coffeemaker when mine died.

Ordered one via fleabay & supposedly it was shipped fedex, untracked.
I thought that sounded impossible, but I waited to see if it'd arrive & it did not.
Contacted fleabay for help, they made a refund & the seller then vanished.

Being curious I tried asking fedex & could not get a clear answer from their friendly ESL speaking rep, so I wonder if anyone here knows...

Do ALL fedex packages get a tracking number ?!?

Thanks for reading !!
