Sports fans have long enhanced their enjoyment of sporting events, but media outlets not familiar with the practice will almost always lump sports such as football and basketball along with horse racing, which takes a completely different type of knowledge. The skills to be successful at horse betting do not automatically translate over to other sports.
There are people who are exceptional at horse racing betting, often knowing who will win based on a horse’s previous track record (literally!) and the age of the horse, the competition, etc. It’s impressive.
