It says that we understand there’s no way a bunch of Ewoks should be able to take down an entire Legion of the Emperor’s best troops.
They should have had blasters and just helped buy the Rebels some time. Would have worked a lot better.
But … the Ewoks did that, right? I mean they kept the Empire busy due to their guerilla (home field) advantage and at least one Ewok …
… had a blaster 😉
