If lebron fans use his stats to say that he is better than kobe?

Well then why isn't Oscar Robinson the GOAT considering his stats or Wilt Chamberlain or Kareem Abdul-Jabar. All I hear is that Lebron gets more ists and more rebounds and blocks and FG% ect. Well how come players like Oscar Robinson aren't the GOAT. Somebody please explain this to me because I don't get it. I believe Kobe is better than Lebron because Kobe is just more clutch, better scorer and has a better will to win. But if stats told it all, Lebron would be better but stats don't tell everything.
