It doesn't matter how much you won or lost. You did not play enough hands to make a statistically reliable determination about your playing ability.

If I got to the roulette tables and bet $1 million on 0 and win twice in a row. That's not enough data to know whether the wheel is rigged.

If I won 50 times in a row. Well, yeah, you've gotta start wondering if the wheel is rigged. That outcome is so unlikely statistically.

If you play for a few days at high limits, you could win a huge amount even if you are playing like an idiot.

And yes, out of 50 online poker sites. Some could very well be rigged.

With poker tracker, or some similar program, a reasonably proficient computer person could probably tell you if the flops and exposed hole cards at showdowns exhibit randomness.

But saying that you played for 2.5 days, tells us almost nothing.

Unless you flopped 100 straight royal flushes in that time. Or unless you can show that there is a distinct non-random pattern to the cards dealt out to players.

You can theorize all you want. But you have presented zero data and the data which you claim to have, will in all likelihood be an insufficient sampling to render any kind of realiable assessment.
