jockey:
(plural: ‘jockeys‘)

Jockeys on their horses in a horse race
A person, normally a young man, who rides a horse in horse races, especially as a profession/job;
(also less commonly) a person who drives/runs/operates a vehicle, a machine or a device,

a child jockey on a camel in a camel race
A horse race jockey must be of a minimum weight of 57 Kg (or 126 lb) to be qualified to ride in a race, and when a jockey weighs less than this, some sort of weight is added to the horse’s saddle he/she rides.
Apart from the glory they get, the winning horse racing jockeys make a lot of money, from $ 4,000 to $ 40,000.
There is a hue and cry over the issue of using children as young as three or four years old as jockeys in camel races which are very popular in the Gulf countries.
There are different kinds of jockeys that don’t ride animals in races: a DJ (Disc Jockey) is a person who plays or introduces music discs at a club, disco party, an RJ (Radio Jockey) is a person who, like a host or anchor on TV, starts a programme on the radio, and a CJ (Cart Jockey) is a person who drives a golf cart or takes care of a fleet of golf carts at a large golf link or course.
