Because that's the way random number generators works. They're not
random at all, they generate completely predictable number sequences
from a "seed": each time you use the same seed, you get the exact same
sequence. In your case, you used os.time() as a seed, which is an
integral number of seconds elapsed since some fixed date, and the fact
you saw the same number ten times simply means your code was ran ten
times within the same second.
