Star wars (and most sci-fi franchises) are fucking awful at giving realistic numbers for what an actual galactic sized armies would look like, often thinking in far too small a size that would be big by relative earth armies. Its partially necessary in order to make the several hundred Jedi who exist not completely irrelevant on a galactic military scale (which they would be), but still laughable when they throw out millions and billions as if they are big numbers in such a massive galaxy.outside of the bad math, can anyone come up with a legit better number, obvious the answer is "more" but i doubt people wouldn't still fuck her hard if she said "6 trillion"
Even Trillions of clones and millions of star ships would still be a small army by galactic scales. The truth is we would have to expand the size of armies up to Quadrillions and possibly even higher numbers than that to have a truly galactic military force capable of fighting on a galactic scale, such is the size of the galaxy.
