That's a hypothesis, certainly not a solved problem. There in't any other evidence for it, besides someone finding that it could kind of work, and some inference about where it was found. Currently there's no explanation for why it needs to be this very-hard-to-cast bronze dodecahedron, instead of just a wooden board with pegs and holes, which is all that would be needed for the video above. Evidence might involve finding contemporary descriptions of these, bills of sales, descriptions of Romans wearing knitted gloves, etc.
