Selection bias, of where they stay. If you come as Tourist in the US, and stay in the center of any large city you are bound to see hordes of drunk people in the weekends... usually on their 20s. But that's not what most of the US is though. 3rd ave in Manhattan, from Lower East Side, to Murray Hill turns like a zoo, (pre covid), around midnight, with drunken 20 something acting like it is spring break. The rest of the areas of NYC are not like that, but tourists are more likely to stay near these places, rather lets say, somewhere sleepy in UES, UWS, Brooklyn, or Queens.
