I think that's a potentially misleading way of summarizing it. Facts are true beliefs; not all beliefs are true. The trilemma only implies that there's no way for me to step outside of my own head and know, beyond the possibility of error, that my beliefs are true. But they may still be true. (That applies recursively to the trilemma itself!)

So if you dig far enough, how accurate our beliefs are is partly reliant on factors beyond our control: if our minds happen to be wired with bad axioms we may be unable to avoid inaccurate conclusions.
