That depends what "it" is 
The default file "000-default.conf" is usually what it says - the default. i.e. what would be used for all domains, if it's not over-ridden by another file.
The naming of 003-status.acegames.de.conf sounds as if you have a control panel / configuration manager of some sort ( people don't usually add numbers to their configs, hence I'm guessing that you didn't name / create that file yourself). if so then that control panel / configuration manager could create the SSL config - if you tell it to. If not then you need to create the config ( or turn off the forwarding (http to https) for those subdomians.
