The configuration of some things (Xorg, fontconfig, systemd, etc.) is done with the help of several files, in the name of which there is some number. For example:

$ ls /etc/fonts/conf.avail
10-autohint.conf
10-no-sub-pixel.conf
11-lcdfilter-default.conf
11-lcdfilter-legacy.conf
20-unhint-small-vera.conf
25-unhint-nonlatin.conf
...

What do these numbers mean?

usually - the order of application.

This is used for several purposes: firstly, the file name is uniqueized in this way, and secondly, sorting is done in this way, which in turn is used for the order / priority of loading configs. Less often, numbering is used for application-specific needs, such as specifying a version or a backup marker.
