He’ll need the same kind of luck to take down Mayor de Blasio.

Councilman Eric Ulrich, a Queens Republican who is mulling a mayoral run, won thousands of dollars gambling last year, new financial disclosure documents show.

Ulrich reported between $5,000 and $47,999 in gambling winnings in his latest report with the city Conflicts of Interest Board.

The actual total was about $10-12,000 and came from slot machine winnings on a few trips to the Resorts World Casino in his Queens district, Ulrich said — including a $7,515 jackpot from a quarter slot machine in April. He said he reported the money to the IRS and paid the required taxes.

“I guess I’m a lucky guy,” Ulrich said.

He’s not the first Council pol to hit the jackpot — Councilwoman Maria del Carmen Arroyo, who has since resigned, brought in more than $5,000 in 2013.

The latest financial disclosure forms also show that at least five Council members had outside income that will be banned under a deal to give the Council a hefty raise.

Legislation passed in January boosted the pols salaries by 32% to $148,500, raises that took effect immediately, but the outside income ban won’t kick in until the beginning of 2018.

In 2015, Councilman Chaim Deutsch (D-Brooklyn) brought in between $100,000 and $250,000 as president a of a real estate firm, Chasa Management.

Peter Koo (D-Queens) made $70,000 to $196,000 in salaries from three of his businesses — two pharmacies, K&F Drug Corp. and Koo & Co Inc., and a holding company, K and F Real Estate, all located in Brooklyn.

David Greenfield (D-Brooklyn) earned between $60,000 and $100,000 as a lawyer at his own firm Greenfield Law LLC, but said he voluntarily stopped taking paying clients in the fall of 2015 and now only does pro bono work. He also listed $5,000 to $47,999 in deferred income from the law firm.

Paul Vallone (D-Queens) made $60,000 to $100,000 as a managing partner at his family’s law firm, Vallone & Vallone LLP. Rory Lancman (D-Queens) also took home $5,000 to $48,000 as an attorney practicing civil litigation.

While income from outside work will be banned, pols will still be able to take in the rental income and pay for serving as adjunct professors that many get, as well as other so-called “passive” income from things like investments.

Some pols can use the raises, since they’re buried in credit card debt. Lancman and Vincent Gentile (D-Brooklyn) both reported between $20,000 and $192,000 in credit card debt.

The filings also revealed that Queens Borough President Melinda Katz paid between $100,000 and $249,999.99 in legal fees to the Mintz and Gold law firm, which repped her in her battle against her ex-boyfriend Curtis Sliwa’s ex-wife.

Mary Sliwa sued her ex-husband and Katz claiming that the two had an affair during her marriage, and that he funneled money to his mistress. The case against was tossed in 2014.

And newly elected Bronx District Attorney Darcel Clark has two relatives working in her office. Her uncle is a community associate for the district attorney’s office, and her sister in law is a secretary.
