The balloon creates internal pressure which makes the helium more dense, so it might in reality be more like 1 gram can lift 5. So to lift a person, say, 72 KG, you'd need a bit over 12 KG of helium, but that's a lot of helium. And, it may seem strange that 10 KG can lift 60 KG, but it's like holding a balloon under water.
