Someone who wins 1 in every 7 races is already doing something right.

The "(7)" beside her name is worth explaining: it means she currently claims a 7lb weight allowance, a benefit given to less experienced riders to make their horses more competitive against seasoned professionals. It is essentially racing's way of giving promising newcomers a leg up while they find their feet, and the fact that she is still at the maximum allowance suggests she is in the earlier stages of that journey. When she does get in the winners' enclosure, though, she has shown she can make the most of her opportunities — and at this stage of a riding career, every winner counts.
