i cant remember where i heard this but would be intresting to find out!

It is more than true, if you can imagine the infinite space of the universe packed with stars and a small planet (Earth) full of sand there are probably more than 100,000,000 times more stars than sand, no its probably even more than that.

over 2500 years ago, Greek mathematicians discovered there waer always bigger numbers
I think the book was called "THE SAND RECKONER" to calculate the grains of sands on earth
you have to estimate the length of beaches the width and the depth that gives total volume of beach
the units have to be right if we measure sand grain in mm millimeter then the volume has to be in cubic millimeter
of course it is only a very rough guess.
then the astomomers have estimated 100, BILLION ( thousand million) galaxies with 100 billion stars
100 x 100 x 109 x 10^9 = 10 ^ 22 stars ( give or take a few trillion)
Assume a beach around the world 6 x 6,000,000m meters x 100,000 meters wide x 100 meters deep = 36 x10^13 cubic meter x 1000^3 cubic millimeters about 3 x 10^23 grains
OH MORE sand than stars Maybe!
see how to work with big or very small numbers
the biggest numbers with names are GOOGLE 10^100 ( ten with 100 zeros) and a "GOOGLE PLEX" 10 POWER GOOGLE,, 10 with a google of zeros, NOW THAT IS REALLY BIG
I have heard an estimate that 10^80 may be an estimate for the number of atomic particles in the known universe. Not sure I did not count them
Infinity is a number without any limit. but there are different size infinities, but that is another story

Within an arbitrary degree of approximation, the two figures are about the same.
Do the calculation if you like. I've done it many times on this site. I'll give you a hint. Either estimate or count the number of sand grains in a cubic centimetre of sand. Get a map of the world and estimate how much coastline there is and what the extent of the sand is. Get a figure in cubic metres. DO the same with the deserts. What do you get? Yep, a figure of around 10^22 (give or take an order of magnitude or two depending on your assumptions). This just happens to be the number of stars estimated in the observable universe.
