Poker Stars $5/10 winrate

[loose passive]

I just compiled my first 1k hands into PokerTracker and I am showing a winrate of +17BB per 100 hands. I do not believe this is sustainable. What might be a realistic winrate be?

Being new at using PokerTracker I am trying to figure out what is the relevant information. I went to auto rate players and it labeled me as Semi Loose Aggressive Aggressive. Is this a good label to have? Is this relevant?

The other stats I have are vpip of about 20% and pfr about 11% and showdown winrate of 58%.

What other stats should I be looking at?

How many hands do I need before I can truly know where I stand?
