As an amateur (but competent) player of both, when I play go it almost feels like I'm playing multiple smaller games at the same time on the same board. Even if I might be struggling in one area, I can make it up in another. So it's very hard for a lesser opponent to beat me, even if they do gain an advantage in one area. Likewise in reverse when I'm playing a superior opponent. I might get in a nice kill, but next thing I know we're playing a different battle on the other side of the board and I get crushed.

So I think there's truth to what you're saying.
