Is it true that most Visitor Visa applications from Jamaica to the United States are denied?

Question

I was told that about 90% of Jamaicans who apply for a visitors visa to the United States are denied...even if they meet all the criteria. Is that true? Do you personally know Jamaicans who have applied for a vistors visa to go to the U.S. to visit a friend (not family) and had their visa request granted?
