You're talking about engines that blunder all the time in difficult tablebase positions. It's ridiculous to suggest they always make zero errors. Sometimes, sure. Often, maybe. Always, no.
The difference between zero errors and 0.1 errors is as big as the difference between 1 and infinity on an appropriate scale. Zero is not a small strictly positive number. It is fundamentally different.

++ Many have, like Shannon's theorem, the Uncertainty principle and many more.
