[Jumanji: Welcome to the jungle] How did Alex recognize the other players after the game?

Alex has never met them in  person and only ever saw them as their avatars. Why would he assume 4 random kids, staring at him would be those 4 players?

What you’re not shown is Alex confronting several groups of teenagers as the players throughout his adulthood. He just finally found the right kids. What a relief for him! Lots of awkward conversations.
