Only 1 of the BlockFi founders (Flori) has an ivy league degree (from Cornell). Zac is a moron who made his wealth playing poker and through a scam loans startup (Zibby).
It's much, much harder to make millions at the poker table than it is to get a degree from an Ivy.
There have been 141 people that have made over a million in 2022 from poker (https://pokerdb.thehendonmob.com/ranking/7339/2) and that doesn't count all of their losses, staking, etc.
The eight Ivies collectively graduate roughly 75,000 people a year.
So I'm not really sure what information the statistic that there are about 140 Poker millionaires in a year vs 75k Ivy grads conveys.
If you do truly think it's no different to the lottery, I'm interested in your explanation as to why these people (a) come from the background they do (a high schooler with decent maths can tell you why the lottery is -EV) and (b) go on to the careers they go on to.
Poker is played competitively both online and in the casinos of every country all over the world 24/7. There are a phenomenal number of players compared to Ivy league students.
Unlike the lottery, it is also largely considered to be a game of skill based on a combination of statistics and social manipulation.
GP is generally implying that because the ratio of players to successful players is so small for a game so widespread that is is very difficult and requires a huge amount of skill to make a significant amount of money playing poker.
Poker isn't particularly luck-based, especially if you play a large number of hands, as eventually everyone sees the same cards on average.
Also, poker doesn't have legacy admissions - the people that win at poker consistently always deserve their status.
