Mayor Bill de Blasio said Monday he’s not ready to roll the dice on sports betting coming to New York.

“Gambling always makes me queasy because I think for a lot of people it’s an addiction … It’s hard to get entirely excited about it,” the mayor said during his weekly appearance on NY1.

He was referring to the US Supreme Court hours earlier striking down a federal law forbidding states from offering sports betting.

“We have to look at it clinically,” de Blasio added. “If the new legal reality is this is going to be allowed everywhere, we have to obviously think about what it means for New York City and how to play the appropriate role.

“But, you know, it’s one of those realities that should be looked at with a certain amount of caution in my book.”

Ruling 6-to-3, the court ruled in favor of New Jersey in its years-long battle against the four major sports leagues — MLB, NBA, NHL and NFL, each hellbent on stopping sports gambling from expanding essentially beyond Nevada.

In 2013, Empire State voters approved a referendum that allowed casino expansion, including the right for four new casinos to offer sports betting.

The New York Gaming Commission is reviewing how the court decision could affect the state, and it would still need to license the four casinos before they can take sports bets.

The mayor wouldn’t have much say in the decision to bring sports betting to the city, but he could try to use political influence if he wants to oppose betting.
