You are correct. The weak polymer resin is used simply to bind and laminate the high strength carbon fibers together to make a structure.

Carbon fibers have tensile strengths on the order of 400,000-700,000 psi (high strength steel is 180,000 psi) but the epoxy resin strength is on the order of 24,000 psi. If the vessel had no carbon fiber in the longitudinal direction it had virtually no strength or structural rigidity in the long direction. I simply can't conceive of anyone actually designing or building such a vessel because it breaks pretty much every design and fabrication rule in the composite world, but James Cameron seems to confirm that the videos are representative of the manufacturing process and the vessel was pretty much a hoop wound design. Which scared the heck out him - and rightly so.

unbelievable.

In this day this level of incompetence and total ignorance is mind boggling.

Oh, wait....

But really, what is the deal with the world today? Politics, technology, AI, germ warefare....we really are on borrowed time if idiots like this can rise to positions of colossal prominence while still breathing air. The gene pool really is not functioning efficiently right now, endangering the whole herd.
