My ten year old daughter asked me this question at breakfast and I initially said yes, but on second thought I was also puzzled.
A quick google gave me these (approximate) figures:
7.5 x 1018 grains of sand in all the beaches and deserts of the world
7 x 1022 stars in the observable universe
If these are reasonable estimates, then there are approximately nine thousand stars in the observable universe for each grain of sand on Earth. (By observable universe, I mean in all the galaxies that we can detect with our most powerful telescopes.)
