So, people should just not bother? Remember, Bezos started in his garage.
On an absolute level, you're right- if he had lived alone, found a golf club and taught himself to play this well without any help, he could be called 'totally self-made' as a golfer. He wouldn't know the rules or have had any tips, but those would prevent him fitting the absolute.
However, if someone has an idea and starts a business or use their talents, it's up to them to be successful, or not. They absolutely rely on their products/talents, customers/fans and the recommendations from customers(sales dollars they generate through their endorsements) if the business is to grow but if they do everything their company needs, they damn sure did most of it on their own. Some have coaches, some don't- in some cases, an appropriate coach is extremely difficult to find. A lot of people are totally unaware of the hard work, time and searching for answers that go into creating the ideas, starting, running and operating a small business and a lot of small businesses become large or even huge in spite of the odds against them. A lot of people hate business owners because they assume the person is exploiting people, soaking up a lot of money and living the high life- that's not true for a lot of people and they didn't start their business to become wealthy- many do it because they think they have an idea for something that's unique or better than what's available, came to hate working for someone else/want to be in charge or because they have the freedom to develop something without worrying about where the money will come from. The lost evenings, weekends, holidays and birthdays with the family, no vacations, working when sick and paying the employees but not themselves is something most people never consider.
Tiger didn't reach this level by sitting on his keester.
