The probabilistic model of knowledge as just a collection of hypotheses that have failed to have been falsified over sufficient testing is the dominant epistemological view today in empirical sciences. Knowing = Probably Is. It's just a matter of degree, so making the statement "it is not true that we know that, but it probably is the case" is ill-formed in the absence of consistent belief thresholds.

Normally I wouldn't say anything, but you did pull a "well, actually" there, so out-pedantifying seems warranted if only for the humour of the situation.
