People need to watch what Jeremy said rather than relying on interpretation.
They said PC goblins come from a type of goblin that lost its fey connection over time. It's a type of goblin that is different from the monster manual goblin the same way psi-goblins from Phandelver are different. The MM goblin no longer represents the One True Goblin, only a specific type of them.
Your PC goblin is humanoid. Its parents were humanoids. Its community has humanoid goblins. Those are represented by NPC stat blocks, not MM goblins.
