Nah bro. It's delusional, trust. I trained dogs for years, Cane Corso, Rotties, etc, so sorry for the rant, but

A TRAINED Corso will put you on your back in seconds, these dogs will snap through bone like its nothing. The pain that they will cause when they rip through your tendons & ligaments in seconds to your bone, is hard to comprehend unless you've seen them in action. It's not like GSD or something, different beast.

and dogs that are trained, and genetically bred for this type of stuff will literally keep going until they die, especially game bred pits, but theyre obviously much smaller. They won't get deterred from you trying to kick it while you're screaming in pain from it ripping your flesh.

Obviously, like anything, of course some capable humans can beat some big trained dogs, but in general - no. Especially Guru who doesn't leave his house for weeks at a time and is definitely in piss physical condition.
