What is a "jet" (physical unit)?
And why does it equal 480 knots or 888,88 km/h, if a jetliner's cursing speed is around 950 km/s? Or why does it equal 0.73 M, if a regular jetliner's cursing speed is 0.85 M?

480 KTAS is the typical cruising speed of wide-body airliners (unaffected by wind).
KTAS means knots true airspeed. This is different from the ground speed passengers are used to (affected by wind).
The Boeing 777 Wikipedia article lists the cruise speed as:
Cruise Mach 0.84 (482 kn; 892 km/h)
Mach number is affected by altitude if the KTAS is kept constant. Mach 0.74 is typical for narrow-body airliners (which typically have a slower cruising KTAS), e.g., a Boeing 737 Classic:
Cruise Mach 0.745 (430 kn; 796 km/h)
But like @bogl said, it's a joke, not a unit unit.
