This is already not true. In general, one Pawn ahead does win in a Pawn ending. KPK is an exception (or at least some positions in it are).

But is is still completely unclear to me how this has any bearing on piece values. KPK is a solved end-game (i.e. tablebases exist), so the concept of piece value is completely useless there. In solved end-games it only matters if the position is won, and having KPK in a won position is better than having KQK in a drawn position. I don't see how you could draw a conclusion from that that a Pawn has a higher value than a Queen.

Piece values is a heuristic to be used in unsolved positions, to determine who has likely the better winning chances. Like in an early middle-game position, where you just lost the exchange, and it will make you feel like you are losing the game because of that fact...
