To separate luck and ability, there is a retake exam.

If there was a tournament-style rock-paper-scissors competition where people from all over the world participated, it would be natural for a person to exist who never lost and won every time, even if he played any number of times. It seems strange, but if I were in that position, I would no longer be able to be normal.
This is really scary, and those who have made their assets grow 100 times through ventures, stocks, and so on, have a certain probability of being "the person who won 10 times in a row in rock-paper-scissors". The method of determining this is to do an additional 2-3 retakes with the winner, and even a person who won 100 times due to luck alone will have a winning rate of 1/27 with 3 consecutive retakes. https://t.co/m0PG1EFtGm This "creative destruction" is a pretty effective technique, I think.
