I train BJJ. You absolutely pick up a ton of stuff in six months.
You also will lose - EVERY TIME - to anyone who has been training for a few years. There is no meritocracy like grappling, because there is no puncher's chance.
A three-stripe white belt will beat the shit out of a no-stripe guy. Even college wrestlers famously struggle.
A three-stripe white belt will get destroyed in seconds against a salty blue belt, let alone the UFC dudes who are black belts.
