I rooted with Kingo, and my phone still says 0x0 (Knox counter) Also using safestrap and it didn't trigger anything.
No, it won't do. The Kingo method doesn't trip the Knox flag. However install a custom recovery to try and use your now gained root privilges for things like Nandroid back ups and flashing mods and it will trip.
Rooting in itself is only really a "half way house", and while some root only applications will be fine and work to do useful things you need a custom recovery flashing after rooting. This will trip the Knox flag.
