That doesn't stand to reason at all. Lactose is not an enzyme, and casein is a structural protein as far as I'm aware. Heavy cream and butter are pretty much exclusively fat, thus both contain virtually zero protein (casein is a protein) and carbohydrate (lactose is a sugar), compared to milk. The nutrition labels show you that.

Those who are intolerant to cow's casein often find they can tolerate goats and sheeps dairy as they contain a different type of casein. There's evidence that goats have been milked by humans for much longer than cows have, thus explaining the higher tolerance to goat's casein.
