yes because otherwise there would have to be "something" left behind in the grinder/mill and there isn't. However my grain mill kicks out fine dust whilst in operation which I suspect is normal and that dust must have a weight so therein will lie the difference though it is probably negligible. Never weighed it though.
14 years experience with a mill tells me this is true. Every time. I mill about 1850g at a time and there is a loss of +/- 4g due to the fine dust (agreeing with elpanadero). I don't ever sift so I can't speak to a possible loss there.
