I'm sorry, but if pk = 3; then pk - 10 =/= 7, pk - 10 = -7, very different.
I used 0-10 as an example but they are really:0-115792089237316195423570985008687907852837564279074904382605163141518161494337

When I say misinformation, now I know you are misinformed, this key :
115792089237316195423570985008687907852837564279074904382605163141518161494338
is an invalid key, but mod n it is the same as G or 0x1. You see, whatever you add to n, it's like adding to zero, if you add 5 to n, what you get is just 5. So no, they are not all the same, if you convert the key above to WIF no wallet will accept it because it has a wrong format. All pk are mod n.
