My aunt went to Finland and she says its common knowledge there that 30% of Finnish men 18-25 died in the Winter War. The USSR offered to trade land to make a buffer zone for Leningrad and Finland said no and they lost that great a percentage of their population as well as losing territory. While Soviet casualties were likely higher being on the offensive, they were proportionately nothing to the Soviets and a major generational trauma for the Finns. But flying Finnish White Death orc shooter 7 billion dead, amirite?
