Yeah they even handed over more territory than the Soviets initially demanded, but they got to retain their sovereignty and reputation. It also led Hitler to underestimate the Soviets, leading to their hard won victory in WW2 against the Nazis, who had willingly opened themselves to war on two fronts.

So it's a potential hinge point in that if the Soviets didn't suck so bad in the Winter War or didn't go through with it, Hitler might not have made what was debatably the biggest strategic error of the war.
