Has dark matter been detected at all yet

I know there are currently many experiments in operation to try and detect it using Germanium at extremely low temperatures.

Shouldn't something have been observed by now? I mean statistically, shouldn't a dark matter particle have come into contact with at least one germanium atom by now?

Is this a bad sign for the theory of dark matter?

Dark matter has always been detected (ever since the idea originated). It just only has been detected by gravitational means.
