Most of your comment was on-point, but you're incorrect here:
> Bankroll management is part of being a skilled player. If you are playing with a roll suitable for the level you are playing at, 20 buy-ins usually, and still meet ruin then you aren't beating variance then you are a bad player, not just having bad luck.
There's a strong suvivorship bias present here. Most poker pros never busted their 20-roll buy-in--that's probably true. Plenty of very good players had some very bad luck and busted a 20 buy-in 'roll.
Some very smart professionals--leatherass, for instance--recommend 100 buy-in bankrolls.
Even then, if you play long enough (as in many lifetimes in aggregate), you will eventually go bust. So certainly it's happend that otherwise qualified players have blown through 100 buyin 'rolls due in large part to variance.
