Winning Algorithms For Rock, Paper, Scissors

Celarent Darii (1561999) writes "The probability of winning at Rock-Paper-Scissors is about 1 in 3. However, people do not play entirely randomly, a study has revealed. People tend to follow hidden patterns that can be used to win more games. A short article on the BBC gives hints on the strategies to be used to get a competitive advantage with your Rock-Scissors-Paper nemesis." Remember, these strategies are for use against people, not robots.

Wait. What?

OK, so two people play this game, each has about the same chance of winning, and that chance is 1 in 3? BTW, nowhere in the original article does it state that.
