Recently bought a used xbox 1 x. The owner didnt reset or remove his account so I deleted hos account because i didnt know how to factory reset the console. When i got home I put my own account and found the old owner's previous games like Fortnite and Hitman 2. I thought games are tied to the account and after removing it i can still play them on my account. Is there a reason behind this? and will they dissapear If I reset the xbox?(im not gonna reset it because it has been working just fine for the past week). Thanks in advance
