What is a "jet" (physical unit)?
And why does it equal 480 knots or 888,88 km/h, if a jetliner's cruising speed is around 950 km/s? Or why does it equal 0.73 M, if a regular jetliner's cruising 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)
If it is at 20°C, then 888 km/h (247 m/s) is Mach 0.72, not 0.74.
But like @bogl said, it's a joke, not a unit unit.

Note also that since the speed of sound depends on altitude (higher altitude = lower temperature = lower speed of sound), and the Mach number is a fraction of the "local" speed of sound, the speed corresponding to a given Mach number will differ according to altitude. Microsoft is probably giving Mach numbers in terms of the speed of sound at sea level, not in terms of the speed of sound at 10,000 m.
