Pabrai is effectively saying that he is 80% directionally right on each investment. Now the comparison does not hold fully when you consider varying time horizons. But that would be the gist.

He mentioned bj21.com so I think it has perhaps to do with some rule variations that differ per table that are exploitable. Perhaps some side bet rules. But the way he speaks about it "51% edge vs 80% in stock markets" (later on) seems to be slightly inconsistent as that are card counting odds to me. Have to say he exploits it quite well for personal marketing as he latches on to the Ed Thorpe bandwagon. Personal opinion: virtue signalling.
