“You win” is a common phrase to refer to something someone has accomplished, whether that be winning the lottery or just getting through difficult circumstances like divorce or illness. Most often used positively such as an upcoming game or job well done; you might also hear it more subtly in negative contexts, such as when applying for job applications that failed or breaking records unceremoniously without properly closing them out properly; more affluent users tend to utilize the term in more formal settings.
