Nope, the only thing that really shows intelligence is 1) if a person understand the basic math that they are going up against and 2) if they are able to find a successful, long term and reproducible strategy that makes them a winner. It's possible to do that with things like sports betting, but it requires a lot of thought and tracking to determine if you're either just lucky with a lot of variance, or are able to produce a consistent profit. Other games like poker clearly have winners and losers, because the house wins if you just sit down at a table and contribute to the rake, however you're more likely to find success at a physical poker table that does not rely on random number generators or potentially manipulative algorithms.
