Rakes from poker are not a big part of casinos income infact they are way down the list compared to other games they run.
Most come from slot machines, roulette tables and so many other such gaming operations. :bird:[/QU
you are right however poker is very profitable because is a safe income , what I mean is that the rake is an income that always be there the casino will never have to pay a jackpot or anything like that regardless of a good run or bad run of a player the casino will not loose a dime.
