Meaning

Voldemort uses this observation as a form of contempt, framing Harry's upbringing among non-magical people as a weakness and a deficiency. In his mind, the Muggle world is lesser, and anyone shaped by it is correspondingly diminished. The statement is meant to explain away Harry's courage and resilience as ignorance rather than genuine strength, the implication being that Harry does not fully understand the magnitude of who he is facing.

Context

This line comes from the graveyard scene in Harry Potter and the Goblet of Fire, the climactic confrontation in which Voldemort is reborn and faces Harry for the first time as a fully restored dark wizard. Voldemort speaks at length to his assembled Death Eaters, and part of that speech involves addressing Harry directly, sizing him up and diminishing him before the duel. It reflects Voldemort's obsession with blood status and his belief that the non-magical world represents everything inferior.
