Again, I'm not familiar with the quote, nor the details of the tech behind DLSS 5.

But even just taking what you wrote, there is a huge difference between lying to the press to get positive coverage/hype and just being outright clueless, which is what the GP comment was asserting. I sincerely doubt Jensen Huang is clueless.
