Did Helios Gracie lose to Master Fada?

I've watched & read lots about gracie jui jitsu. But I've recently heard about Master Fada and his academy taking on the gracie academy and winning including FADA beating Helios
Why do the gracies never mention this maybe Gracie jui jitsu is not magic like some people think
I've trained muay thai & jui jitsu & in a normal st fight or bar brawl id prefer muay Thai because id be trying my hardest to stay on my feet.
obviously in a 1 on 1 fair fight it would be jui jitsu what's do u thinks best for real life(where u could also be outnumbered ?)
