A properly generated IPv6 ULA (Unique Local Address) prefix is unlikely to have collisions.

A randomly selected subnet from 10/8 is also *unlikely* to have collisions.

The probability of collision between two subnets in 10.0.0./8 is orders of magnitude higher than between two IPv6 ULA networks (which is 2*10^-12).

But there's a defined difference between "unlikely" and "guaranteed".

Indeed. "Guaranteed" means it cannot happen. "Unlikely" means it may theoretically happen but it won't practically happen in your lifetime.
