According to wikipedia:
"Survival horror is a subgenre of action-adventure and horror video games that focuses on survival of the character as the game tries to frighten players with either horror graphics or scary ambiance. Although combat can be part of the gameplay, the player is made to feel less in control than in typical action games through limited ammunition, health, speed and vision, or through various obstructions of the player's interaction with the game mechanics. The player is also challenged to find items that unlock the path to new areas and solve puzzles to proceed in the game. Games make use of strong horror themes, like dark mazelike environments and unexpected attacks from enemies."

You're not wrong, but you took a very roundabout manner to explain the concept and yet didn't really do it much justice.
