Am i light enough to be a Thoroughbred jockey?

I'm a 20yo female i'm 5'5 and weigh 110 pounds. I've already started off as an exercise rider for my local racetrack here in Phoenix. I don't come from a family of jockeys but i've dreamed of becoming one since i was little. Do i need to shed anymore pounds? I love the horses have always had a pion for them though i know that isn't enough. My ultimate dream is to ride a Triple Crown winner and/or a Breeder's Cup race winner. I plan on learning what i can from older more experienced jockeys preferably retired. I've already started a really strict diet.
