The bit about "UNC Paths" is a bit simplified. The "$" shares are administrative shares. They're created by default, you can delete or disable them (though, if you delete them, they'll be recreated on a reboot). You can also add normal users to them. It should also be noted that while the single driver letter ones are automatically created, the "$" at the end just marks them as hidden. You can create your own hidden shares if you ever want to.
