Obviously. But one banks on the probability that that only happens rarely.

you are right, but as anyone said,
a block has a fixed size and a file can niot fill all of its bloks
if you have the block size 4096 bytes
and you have a file of 12289 bytes you will have 4 bloks
but only a byte from the 4th block will be used, the rest of 4095 will be
free, but no other file can use them because this is a block of the
specified file.
so infact the file will have on the hdd 16384 bytes.
