Correct. Remember why MMA was started: bring your style, no holds barred, and let's see who wins. Effective fighting wins. They had to modify early UFC rules for safety, and they added weight classes, but essentially it spawned a hybrid fighting form of Muay Thai and Brazilian Jiu-Jitsu (or similar forms) that is now arguably its own martial art. You now have an effective fighting style for the street or for fighting an opponent with whom you have no experience, or of whom you have no prior knowledge. It isn't perfect; no one wants to get stuck grappling during a street fight while opponents come or odds change. And granted, the style derived from competition under the rules of the octagon does not mimic the street or account for fighting multiple opponents or fighting with other people on your side, or with weapons. But most modern fighting advocates would agree, I think, that a truly effective universally applicable real-world fighting style combines forms of striking, clinching, throwing, and grappling. The tats and the trash talk are just a cultural part of the lifestyle and the entertainment side of the show.
