The clip is labelled as a confirmation sound from Da Fu Weng 4, the Chinese-language board game better known in English as Richman 4, where players move around a board buying property and building wealth. Short interface sounds like this one are easy to lift from older games and reuse, and they have since circulated on soundboards and in short-form edits as a shorthand for a selection being accepted. Its appeal has lasted because the sound is instantly recognisable as game feedback, even for viewers who never played the original, and it adds a retro touch without needing any explanation.
