That's not accurate.
Neither is that.
1.) You are aware that fingerprints are still used as police evidence. They are quite unique. I presume you refer to cutting of a finger. This is true. But you may consider also a face-id unlock with a gun pointed at you.
But this is not the point, for a lost or stolen phone, is either system is good enough and neither you can crack.
2.) Fingerprint needs dedicated hardware. Face-id you can do with a cam.
I wonder why Apple didn't do both on the expensive devices.
