Cron not disabled? (Every WordPress site uses native cron)_ What?

I am not sure what it means: '‘Every WordPress site uses native cron’'
Because in order for linux cron to work or to have an effect, then wordpress cron should be disabled in wp-config.
It is not disabled. Am I missing something?

Seriously.
In wp-config, wp cron is NOT disabled. How does Linux native cron replace the wordpress cron if the wp cron is not disabled?
