Basically that means the controllers support direct input (possibly xinput but doubtful) right out of the box which means you should be able to use them right away provided you have some way of connecting the controllers (BT or USB). The DS4 did the same exact thing.
However most games now a days only support xinput so you'll need to use something like x360ce, xpadder, or even install third party drivers (like DS4 Windows) to work with those games.
