Indeed, FLAC uses models to predict signal and then encode the residuals
which are, hopefully, rather small and require on average fewer bits.
For perfectly random noise any model except "verbatim" will yield
potentially large residuals, as large as the signal itself, that's why
very little or no compression is attained. However, headers might
increase slightly the signal length.
