“”If any man sin we have an advocate with the Father, Jesus Christ the Righteous”
John is writing in 1 John 2 to “ My little children” believers, who have an advocate, not the world.
Proof is 2 Peter
2:1 But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them--bringing swift destruction on themselves.....2:17 These men are springs without water and mists driven by a storm. Blackest darkness is reserved for them.
This passage says Jesus both bought them and that they are doomed.
