Yes, although a better way of saying it is that it is not the helium which has lifting power, it is the balloon. A balloon has lifting power equal to the weight of the air displaced by the volume of the balloon. From this, you must subtract the weight of the balloon and its contents. Helium is one of the few materials that allows you to wind up with a positive net lift.
(Also, for this to work, 1kg of helium would occupy a balloon much larger than 10cm^3).
