This is very technically correct but also misleading.

In the last test flight, Starship reached a velocity of 7.3km/s. Orbital velocity is 7.8km/s.

Why didn't they make it to 7.8km/s? Because they choose not to. Starship had the fuel, control and capability to burn a few more seconds for another 500m/s.

It also (barely) survived re-entry and achieved a fully controlled, powered, soft splashdown.
