If you are well capitalized, with a few years of living expenses, and about 5-10 years of experience than the success rate rises. The stat's count every noob that put $100-$500 into a Fx or penny stock acct and made a 1-3 month run at it with no experience & unrealistic expectations.
The typical background of an independent trader making a living is they first put together some decent operating capital from investing & trading over the long term while working full time. Their trading business is funded from profits they already made - a positive feedback loop.
