CheatEngine needs Root / UAC admin. If you are root, you can do almost anything on your OS, including reading/writing another program memory space. I guess a common usecase is when debugging an executable. Read/write another program’s memory space is commonly used in video games hacks but nowadays they are doing it using drivers to access the Ring 0 (Kernel Mode) and have full control over the OS and bypass user-mode anti-cheats.
