This sound comes from Minecraft, where it plays as the notification for finishing a challenge advancement, the tougher tier of in-game goals that appear as a toast in the corner of the screen. Players first heard it in regular survival and creative play, but it quickly moved beyond the game as creators clipped it for YouTube videos, streams, and short-form edits. Its appeal is simple: the melody is instantly recognisable to Minecraft fans, yet clear enough for anyone to read as a success cue, so it keeps working as a shorthand for finishing something hard.
