It's in the rest of the post.
Regarding making $200k and making a living, I don't know enough to spout off real-life examples, but you must understand that the $200k is only revenue, not profit. They still have tournament related expenses (maybe they are sponsored for these? Not sure), other training expenses, and taxes on their revenue to pay. $200k in winnings may sound like a lot to you and me, but I'd be surprised if they actually take home even half of that.
Depends on the state they live in how much they get taxed too. Some professional athletes will have their official residence in a state that has no income tax.
For someone making $100K-$200k a year, state income taxes aren't all that significant. For example, in California, which has some of the highest state income tax rates, a single taxpayer earning $200k would pay about $16k in state taxes. Federal taxes would be the major hit.
