It depends on the type of interview. Generally, by the time I interview someone, they're past the "do they have credentials" stage. So my interview is geared to getting to know the candidate and if they would be a good "fit" with the company.

Generally, I only use the "interests" section as a way to guide the interview to those topics. If they can't talk about those subjects, that's bad (e.g., I had one interviewee who listed boxing as his hobby. I asked about several recent PPVs and HBO fights. He hadn't seen any of them. If you don't actually watch boxing, don't list it as a hobby). But if they can make interesting small talk about it, it's +EV.

That said, what you're asking is if poker is "taboo" anymore. I.e., no one would list porn or marijuana as an interest, is poker in that category? IMO, no. That said, I am a poker player, so I'm biased. But my company even had a poker night fairly recently. So I don't think it is considered a den of thieves, cheats, and liars.
