If it was White to move again, they wouldn’t win: 9…– 10.Ke4 Kd6 11.Kd3 Kd5 12.Kc3 Kc5= as was seen before

10.e4 White can play back and forth in the 6-8th rank, but Black would just move their king back and forth in the squares: e8, f8, f7 and when the White king goes back to c3 to capture the trapped rook, the Black king would always be in time to defend the rook in c5. For example: [10.Ke6 Kf8 11.Kd7 Kf7 12.Kc6 Ke7 13.Kd5 Ke8 14.Ke4 Kd7 15.Kd3 Kd6 16.Kc3 Kc5= as was seen before
