No, because Steam users have completely different Pcs and many are not beefy enough for VR. But all the ~120 million PS4 owners could use the PSVR, so it's logical to use percentages. You can judge success however you want, but in my book 5% is not very much.Why do people judge PSVR's success this way? It's super stupid to do so. Nobody thinks VR headsets were going to be bought by the majority of PS4 owners. It'll be like judging PCVR based on the percentages of Steam users.
