The 1's and 2's show how many hard links are associated with that particular
label. In the case of files, it refers to the number of hard links to that
same file data. In the case of directories, it refers to the number of other
directories contained within.
That means that files will start off with a count of 1. Directories always
start off with 2 since they always have '.' and '..' It's not reliable to
use that to detect if a label is a directory or not, though, since a file
with another hard link would show up as '2' as well.
A more reliable way of detecting the type using 'ls' is to look at the first
character in the permissions. Note that for all of the regular files, the
first char is '-' but for the directories, it is 'd'.
