What does it mean to say "since the magnitude of actual momentum is smaller than uncertainty, the value cannot be defined"?

Original question:

Uncertainty in the momentum of an electron is $$2.6 \times 10 ^{-23}\, \mathrm{Kg m s}^{-1}$$. Suppose the momentum is $$1 \times 10^{-24}\, \mathrm{Kg m s}^{-1}$$. Is there a problem defining ths value?

Answer: Since the magnitude of actual momentum is smaller than uncertainty, the value cannot be defined.
