Zaroff lost to Rainsford in the end because he was too confident in his skills. This all helped him overcome the challenges of killing his prey. He knew how to set traps, follow trails, and fire a gun accurately. He had to survive through many fierce battles with animals, and he did that by using his spectacular hunting skills and his vast amount of knowledge.

Zaroff is a cunning hunter who could hunt down any animal in the world, with the exception of humans. If the story had been longer, there probably would have been a battle of right and wrong in his conscience and that probably would have become a hardship he had to face. In the end, he sort of lost his conscience when he killed Zaroff in cold blood, but that was already at the end of the story. Also, he had a vast amount of knowledge about surviving in the wild, which aided him when he had to live in the jungle.

He did not make impulsive choices like most people would do in a situation like his instead, he made logical choices that he knew would benefit him. Rainsford survived through it by keeping a clear head even when under a lot of pressure. What Rainsford had to survive through was a game in which he was a prey being hunted down by a hunter.
