Just understand that any house edge will always take your entire bankroll. Even if you play with a 0 house edge, you will still lose sooner or later due to the fact that the casino has restrictions on the maximum bet.
In this case, bonuses, cashback, etc. will give you an advantage. Better to play poker against people.
Actually, if there were a 0% house edge casino I think we would have chances to win on long run, because it would mean random outcomes without any advantage for one side or another. For that reason, there isn't any 0% house edge casinos available, otherwise the casinos would be under constant risk of losses on long run, turning the business into an unsustainable one which couldn't be maintained anymore.
On the other hand, 0% house edge games would be a great concept for PvP decentralized games. That is, games which wouldn't have a casino platform as middleman, so there would be 50% winning chances for both gamblers competing against each other.
