It sounds like you've misunderstood the statement.

They're not saying the lab-leak is more likely than not given the CCP likes to hide things. They're saying the lab-leak becomes relatively more likely after conditioning on the information that the CCP likes to hide things.

That's completely reasonable if we think the tendency to hide info is going to asymmetrically impact the investigation into a leak more than an investigation into zoonotic origins. It's also reasonable even if we think they're going to hide things whether or not it really was a leak, since the impact can still be asymmetric.
