He was being Dominated by the whole team not dominating the whole team.

The thing with spy is just getting comfortable with the fact that you need to know when you should go in for a stab, and always avoid walking into people, and never NEVER look directly at people. Also bots have some minor errors where they are very observant making spy rather hard in bot games. Just play spy on something like a payload or cp, I find ctf is pretty hard to play spy on because everything is linear and you have to go charging at the other team.
