Wrestling is what you would call a performance sport. It's more of theatre than sport. Is it real? Well depends, they will wrestle alright, but the props they use are never meant to incur fatalities. They use a script to make it interesting and also what you call Kayfabe. (Google it). The wrestlers are highly trained professionals who use mock combat and catch wrestling. They are stunt men as well and reality is emphasized by camera angles. But they do also get hurt as well. Any stunt man can attest to that.
