Take a look at *most* of the betting sites, and CS:GO sites for example, they all use "Provably Fair" dicing and whatever the fuck else. Sure, I do not think it would take a lot of knowledge to set it up on your site, change the rates so house wins, like any gambling type, because everyone wants to win and profit. I do not think it is also done in the seating or board, but just by the algorithm code itself, I am like 50% sure you can find it online somewhere as well, as to which so many sites use it. Sure you could pay someone to make a custom gambling algorithm and all but that would cost a lot, but it would still have the same 'rigged' affect of house winning often.
