Diversity means everyone is the same but they look different:

"Player characters, regardless of race, typically fall into the same ranges of height and weight that humans have in our world."

New character races don’t have the Ability Score Increase trait that Player’s Handbook races have. The new races instead rely on a special character-creation rule that allows a character to increase one ability score by 2 and another score by 1 or to increase three different ability scores by 1.

Generic Humanoids bear the words “Any Alignment,” reminding the DM that such people have vast moral range.

That one word—“typically”—reminds the DM that the alignment is a narrative suggestion; it isn’t an existential absolute.
