Not necessarily. I’ve had UPS labels be in that state until the item is delivered.
Having run a couple of The UPS Stores for about 5 years up to about 5 years ago that is an extreme, almost infinitesimal rarity because it means scans were missed at minimum of 3 locations depending on origin and destination. If you are thinking of USPS (mail) that does happen quite often but with UPS and FEDEX an extreme rarity to have zero scans other than delivery.
