As has already been detailed in other such threads, Chess whilst recognized as a 'sport' by the Olympics Committee for decades has never been invited to the games.
Similarly, Bridge, which has international leagues and global player rankings has also never been accepted after some intense lobbying. So, the idea poker would be accepted as opposed to Chess or Bridge is wishful thinking.
Personally, I find the idea of proposing poker (or e-sports etc. etc.) for the Olympics fairly ludicrous. The impression I get (fair or not) is such an idea is generally proposed by those who have never played sports at a competitive level.
