Walruses are fat because the blubber helps with cold temperatures and also if you've watched videos with polar bears and walruses, it helps protect them from the bears claws and teeth and also from attacks from other walrus tusks. walruses swim in frigid cold waters so having an extra layer would be helpful.

They have blubber (fat) under their skin which acts as insulation so they keep warm, even in cold temperatures like that
The thick layer of blubber round their body is to insulate the walrus from the intense cold.
Three arctic animals that have blubber besides a polar bear are seals, walruses, and whales. Blubber is a thick layer of fat that helps these animals insulate their bodies and stay warm in the cold Arctic waters.
Also known as blubber, this layer helps the walrus to keep heat inside its body instead of having the heat radiate off of it.
