First of all, uptime doesn show how many users there are logged in. Second of all using ps command this way is useless.
To show what and how many users have logged in into the system use:
Code:
 
who

if you want to get user processes based on your ps command, I rather would use:
Code:
ps ux -U abc123

Good luck.
