It differs with sport and country. The vast majority of them – probably well over 95% – do not get paid enough to make a living from the sport. Here are some stories:
From Britain, the story of the captain of the British women’s handball team. (Handball is still in its infancy there.) She married a male handballer two years ago – a really nice guy – and they still haven’t managed to spend more than a month together. A heartbreaking interview, and yet I’m so jealous of how close they are. They also talk about the funding situation, and how the athletes coped with it. He didn’t manage to make the national team, but they said that even if he had, one of them would have had to drop out since the money they were getting from the national team was less than what they would have gotten from a more normal part-time job.

Several athletes serve in the army. Mike Dixon (biathlon) is a combat engineer in the British armed forces, who works as a fitness instructor and motivational speaker. Václav Chalupa, Jr (rowing, one silver medal) is a captain in the Czech army and a skilled repairman of agricultural machinery.
Shooters typically don’t get paid much. Canadian (now Seattle-resident) Dr Susan Nattrass could tell you about that. After earning a masters in 1974, she went to one Olympics in 1976, then worked at various jobs in teaching, admin, etc before going back to get her Phd. After becoming Dr Nattrass in 1987, she returned for her second Olympics in 1988, and then four more Olympics. She now has her own medical research facility for osteoporosis, so she sure aint giving up her day job. Of course, she’s exceptional – I think most shooters tend to have jobs in the armed forces and police forces. I don’t know if any Olympic shooter ever was a sniper during warfare, but it’s hard to imagine that that’s not the case.
PS: Dixon, Chalupa, Nattrass have all competed at at least six Olympics.

In the old Soviet days, many athletes had jobs in the police & armed forces. But many of those jobs weren’t mere sinecures like the Western media loudly trumpeted. And those days are long gone in any case.
In India, the worst nation in the world at the Olympics, the top athletes often have jobs at the railways – ticket collector (work at night, train during the day), clerk, etc. http://www.nytimes.com/2010/02/10/sports/olympics/10olympics.html
Here are some other articles on Olympic sacrifice and suffering – e.g. US pairs skater Mark Ladwig speaking of juggling ten credit cards, etc.

It should be somewhat clear that the financial outlook for the average Olympic athlete from Africa or other third world countries isn’t that great, either. Although the sad tale of illiterate South African marathoner and 1996 gold medalist Josiah Thugwane ( http://zar.co.za/thugwane.htm ) who was with his family repeatedly threatened for his money after the Games (”...his wife was greeted at the gate of their home by the severed head of a monkey impaled on the garden railings…”) is exceptional for its brutality.
