This is just a guess, but I think a UFC level MW (probably walks around at over 200 lbs) would beat any untrained guy. Size & skills both matter, but at the size of a UFC MW, I think they're big enough & skilled enough to be able to overcome any untrained guy.
What I will say is I'm pretty athletic & fit compared to most people, on my first day of BJJ they had me rolling with someone much smaller, I was tapped out very quickly. Of course BJJ & a street fight are 2 different things, but skills do matter a lot IMO
