Do note that win rate on its own doesn't mean anything. You can have a win rate of +90% but still lose money. You do need to do some other calculations (profit factor, risk:reward, expectancy, ...)
Regarding the funds, all you can do if you have no funds currently is save up until you do have saved enough funds to start out with. Take an extra job (or 2), cut all costs that aren't completely necessary. The advantage of Forex is that you can trade very small size so you don't need a super large amount of money, however don't expect to make a noticeable income on a $1000 account.
