No, you're safe. You are seeing yourself logged in to the computer with the systemadmin user. It's normal for the PID to be different from the example, it is a Process ID, generated when the shell is launched, not something static. If someone was logged in from outside, you'd be seeing an actual IP address in the comment, instead of (:0)
