No, it is NOT the same thing as sea-sickness. I do not get sea sick, never have. I also don't get car sick if I'm a passenger reading a book or something. Never have. But turning, specifically TURNING, in VR, induces nausea.
When Oculus was first released (dev) games allowed for "free walking" FPS games which invoke a specific kind of nausea that is different from roller coaster style movement. It's the reason why almost all games are teleportation based now... Because this problem as I understand it affects the majority of people, even those who don't experience the other VR nausea which IS similar to sea sickness. This turning / angular momentum nausea does not attenuate with time. It's a huge problem with VR, and one which there is no solution for currently other than the poor "teleportion" movement mechanism.
Not entirely sure about how trustworthy it was but I think I've seen some kind of a study that claimed it affects something like 30% of people. Doesn't really matter if it's majority or just 30% though, still too much to ignore and not all games are able to offer multiple locomotion options.
Also depends on where you draw the line. I've never gotten sick from VR personally but the movement can still sometimes feel weird to me.
