There are players who have HUGE samples to work with & use HEM to check out if things are within a somewhat expected range. I've never heard one (with a decent sample size) who would suggest that something is astray.
If you're talking more about Tournament play... then 'yes', some players are going to be luckier than others. I've seen some players who are just as good as (if not better than) who've gone deep in many, many large online tournaments 'but' who have unfortunately never (or rarely) been able to close one out (ie. they'll get deep... say 20-25left from 1,000-3,500 entrants) and then BOOM.. the time the KK v 99 doesn't hold up is right then.
I don't know if they are 'unluckier' but perhaps that standard variance just hits them at the wrong time. Over a large enough sample size though, I think it all evens out (unfortunately I believe the size of that sample has to be quite HUGE).
As mentioned by someone above, you could probably spend your time on something a bit more productive (as far as becoming a better player) instead of focusing on some statistical match-ups of some allin hands in a SNG (< although I've done this too before quite awhile ago, lol).
