There are formulas to calculate that, but let's quickly compare with some of my stats:

I've logged 422 hours of 0.50/1 Hold'em with StatKing, making a 737 BB profit. The stats module tells me there's a 98.9% chance I'm a winning player.

So you should be a winning player with > 99% probability or thereabouts if the amount of time you have used is roughly equal to or less than mine
