Rousey's comments come after her last two fights lasted a total of 30 seconds. Her most recent opponent, Cat Zingano, only lasted 14 seconds before her unbeaten streak was ended in what was the shortest title fight in UFC history.
Rousey attributes these dominating performances to the fact that she was raised to be a fighter, while the other women in MMA started later in life.
"It's not that they're lacking anything so much that they decided later in life that they wanted to be a fighter," Rousey told ESPN. " A lot of these girls already developed a personality and had a life and one day decided, 'Hey, I'm really good at this stuff, I should give it a try.' Whereas this is literally what I was raised to do.
"I have so much more mat time and experience than these girls, they just can't catch up."
Rousey is undefeated since making her MMA debut in March 2011, and since her demolition of Zingano there has been much talk regarding whether she could match male bantamweight fighters.
Analyst Joe Rogan has asserted that she could beat "50 percent" of male fighters in the same weight division. Not surprisingly, Rousey backs herself to beat any fighter, regardless of their gender.
"I never say that I'm incapable of beating anybody because I don't believe on putting limits on myself," she said. "If we are just talking about what in the realm of possibilities is possible of who I could beat — well I could beat 100 percent of them.
"You can't tell me there's a zero percent chance that I can't beat anyone on the planet, so I'm never going to say that."
