No
Kasparov lost because he did not play well later.

No

There is certainly no reason to lose the game so fast like Kasparov did.

Here is the game

[Event "New York man vs machine"]
[Site "New York"]
[Date "1997.05.??"]
[Round "6"]
[White "Comp Deep Blue"]
[Black "Kasparov, Garry"]
[Result "1-0"]
[PlyCount "37"]
[EventDate "1997.??.??"]

1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nd7 5. Ng5 Ngf6 6. Bd3 e6 7. N1f3 h6 8.
Nxe6 Qe7 9. O-O fxe6 10. Bg6+ Kd8 11. Bf4 b5 12. a4 Bb7 13. Re1 Nd5 14. Bg3 Kc8
15. axb5 cxb5 16. Qd3 Bc6 17. Bf5 exf5 18. Rxe7 Bxe7 19. c4 1-0

I think that there was no reason to play 16...Bc6 and 16...Nc7 is better.

White has a better position at that point but there is no reason that white will
win so fast.

Kasparov did a lot of mistakes in the game
8...Qe7 is not considered to be the best move by theory.
