Bob has a forced win if the starting position \( n \) is a P-position where the first player loses; these occur exactly when \( n \equiv 0 \) or \( 2 \pmod{5} \). Up to 2024, there are 809 such integers, so the answer is \(\boxed{809}\).

Forced-losing positions (P) for first player occur when \( n \equiv 0 \) or \( 2 \pmod{5} \);
Counting \( n \le 2024 \) with \( n \equiv 0,2 \pmod{5} \) gives \(\boxed{809}\).
