A person who rides horses (mainly thoroughbreds) is called a Jockey
The rider of a horse in a race is called a Jockey.
He/she isn't, the horse is. The handicapper looks at the previous form (results) for all horses in the race and decides what weight each horse ought to carry to, in theory, make the race a dead-heat. The jockey and tack (saddle etc.) are weighed and anything below the handicap weight given to the individual horse is added as weights, into the weight cloth. Jockey and tack are weighed again after the race to check the weight, allowing a little for sweating of the jockey.
In the United States, in Thoroughbred racing the jockey wins 10% of the horse's winnings for a given race.
