I don't believe this is true on iOS, unless there was a recent change I'm not aware of.

Right now, tapping power five times on my phone running iOS 16.1.1 opens an "emergency" mode, which allows anyone to call 911 or see my "Medical ID". It also has an option to "cancel" this mode, which returns the phone to a normal locked state but forces a passcode to unlock (i.e. Face ID will not unlock the phone in this state).

Check your "Emergency SOS" settings. For both "5 taps" and "hold power and volume" there is a setting to control whether they call emergency services.

If those are off then they just open the emergency screen. If those are on then they open the emergency screen and start a countdown to automatically call emergency services.

On my phone they are on, but I don't remember if I set them to that or they came that way.
