TLDR: Players are more likely to pick the move that just won.
To exploit that, the best strategy would probably be to always pick the move that wasn't played. Should give you an edge until your opponent notices your pattern :)

Since humans are bad at random, "just play randomly" doesn't really work; humans don't have access to "random" to play that way. So you often do get into the sorts of strategies you mention, to compensate for this.
Besides, it's more fun this way.
I believe there's a natural intuition for reading the expected movements of the other player, and have seen this reproduced (if anecdotally by only testing between myself and her, and not recording results) hundreds of times. Like you, 10-12 streaks of ties were not uncommon, certainly less common than statistics would seem to dictate.
