In the first, scientists found that all four species of the great apes are capable of making sophisticated risk/reward decisions. When presented with a choice between a small piece of banana with a known location or taking a chance on lifting one of several cups in the hope of finding a larger piece, the apes make their decisions based on the probability of success and the discrepancy between the size of the small and large piece. The larger the hidden piece, the more risk they are willing to take to find it. Sounds like calculating pot odds to me.
In the second, researchers found that chimps in the wild take into account whether the other chimps already know about a danger before deciding whether to sound a vocal alarm. Awareness of other players' states of knowledge is a critical poker skill. Was that guy here when I bluffed in this situation 30 minutes ago? If so, was he paying attention, and will he recognize that this hand is very much like that one? It seems that chimps have at least the rudimentary ability to process this kind of information.
In both of these traits, I'd have to say that they exceed the capacity of at least some human poker player, who display zero ability to perform such complex tasks.
