Incorrect. PC games, software, console games - many of these have not and likely will not be cracked. That's not to say there aren't many out there but if you have paid attention to information dripping out of cracking groups, you'll see it's becoming much more difficult to get around DRM.
Similarly, Cinavia works. RTMPE works.
It doesn't mean they should be there. It doesn't mean that adding the DRM doesn't cause annoyances to legitimate consumers. But that blanket statement that whatever DRM you add is ineffective is simply wrong.
Edit: quick example - ps4 released Nov 2013. Can you play pirated games on it? Nope. You can install linux but it's likely a number of years before piracy can happen.
