If that is all the hands you have, there is no way you can deduct your true winrate from it. In fact I am pretty sure that you are indeed running good playing a very swingy aggressive style of play. I say this because I believe winrates of 20ptBB/100 over the long term are extremely rare to non-existant at anything but the lowest stakes.

Lets say your unknown true winrate is 10BB/100(which is very good) and you play your first 5000 hands. If we use my SD of 30BB/100(what is yours?), then we can make the following statement.

"We can be 99% sure that your results will be within -2.7BB/100 to 22.7BB/100 after having played 5000 hands"

or

"We can be 95% sure that your results will be within 1.6BB/100 to 18.6BB/100 after having played 5000 hands"

As you can see the range is quite wide.
