I don’t know how these things are counted, I must admit, but I’d be very interested to find out.

My understanding is they are whole drive writes as the controller uses a wear levelling algorithm. If it didn't and since the drive is used by the cpu and OS for other things than just storing your images then I don't think it would last very long.
Additionally the drive is over-provisioned with spare blocks which it can use if the wear on a particular block passes a certain threshold.
Like most things in electronics there is a lot going on under the covers.
