Is it possible to get 100% accuracy in a game?

Yes it is possible to get 100% accuracy see my game I played as black.

neither side got even 95%
1. e4 1. e5
2. Cf3 2. Cf6
3. Bc4 ? 3. Cxe4
4. Cxe5 4. d5 !
5. Bb5+ 5. c6 !
6. Ba4 ?? 6. Dg5 !
7. Cg4 ? 7. Bxg4

No they made a few inaccuracies. Yours isn't based on cap score. So your acc. could be exaggerated.

yes watch
