Does the removal of German border control from 15th June apply to third-country nationals legally residing in these countries?

It is announced that Germany will remove travel controls for entries from other EU countries, the Schengen-associated countries, Norway, Liechtenstein, Iceland and the UK on 15th June (https://www.schengenvisainfo.com/news/germany-to-lift-internal-border-controls-on-june-15-prolongs-those-with-austria-until-november-12/).

Is this based on your nationality or the country you are departing from? For example, if you are a third-country national legally residing in one of these countries (as a long-term international student), would you be allowed into Germany from 15th of June or would you be subject to the easing of restrictions at a later date?
