They might be studs on the "pro wrestling" circuit ... but even the most talented "real" wrestlers in the WWE would get ROLLED UP by Team USA's olympic wrestling team ... so says Kurt Angle.

Angle would know ... he won a gold medal in freestyle wrestling at the 1996 Olympics.

So, when it comes to hardcore competition -- not even guys like Seth Rollins, Dean Ambrose and Finn Balor can compete with Team USA's Daniel Dennis, Tony Ramos and Tyler Graff.

BTW, we asked Kurt if he would consider another Olympic comeback attempt -- but he shot that down hard saying he's too old and would "get my ass kicked."
