True Win Rate thoughts: Why can't I be a NL200 pro?

[HoldEmKillah]

I don't necessarily mean me but I mean anybody. I'll use my own stats as an example of what I mean. Nevermind the fact that I've only logged 9,000 hands at NL200 since this is just an example. A good player should be able to replicate these numbers after 50k or 100k hands. So why can't a good player be a pro making a SICK income off the NL200 fish? I never realized how much money can be made from just the 200 tables until I checked out my True Win Rate on PT today. Here are my stats after 9389 hands at NL200 on Party:

BB/100: 8.57
MT Ratio: 2.58
table hours: 50.45
True Win Rate: $63.76

So let's say that over the course of year someone makes slightly less than this...let's say $60/hr and plays 40 hours/week for 50 weeks (2 weeks vacation) then that's $120,000/year salary just from the 200 tables.

Increase your MT ratio or improve your BB/100 and it goes up even more. Beat up the NL400 tables for 6bb/100 and you're probably talking close to a $200,000 annual salary.

What am I missing here? Is this right?
