When I read your comment, I thought the reason Stockfish won was because the computer found an innovative tactic that a human would not see.

Watching the game, it looks like if there was a human player instead of the Houdini computer, the human would be easily able to force the game into a draw instead of a loss.

Nonetheless, as an intermediate chess player, the games were fun to watch because of how different the play style computers can sometimes have versus humans.

That's because it WAS a draw if Black played correctly - by blocking all the pawns from advancing and only moving the rook back occasionally if attacked by the bishop (although probably it would have remained a draw even if Black had given up the exchange. There was no way for white to get in there.
