From your measurements, I would assume you're quite thin ... there are a lot of women who are taller, stronger, weigh more without being fat, etc.
I could probably take you. If I were still at my physical best (5'9", 170lbs, very strong back then) I would leave out the "probably."
Could your 5'3" girlfriend take you? Maybe, maybe not. What does she weigh, how compact is her muscle structure, these sorts of questions will decide whether or not she could out-wrestle you. Moreover, has she had any wrestling training?
If you were 6'4" and 230 lbs, I would be less absolute. But I'm definitely sure there are women who could knock you down and keep you down.
