It is technically true, though. Autorotation only provides some control while going down (and the adds inertia helps, too,) but generally they won’t be getting back to an airport or something the way an airplane could.
The way it works is they pitch the rotor blades to collect head speed on the rotor and then flair just before the crash, using the rotor’s inertia to make one last bit of thrust. They can use some of the energy for control and to get someplace safe, but they’re usually not trying to go cross country.
Done correctly, in a clear area, they can survive. But a clear area is a lot easier to find for a helicopter than it is for
Usually helicopter crashes are fatal, however. Most crashes are caused by pilots though, for example pilots that elect to fly through cloudy mountains….
