>20 shots at goal is worse than 10 shots at goal, it means the players are "trigger happy" and jump to soon in their attempts to score.
0-5 shots, the team is being dominated and is having trouble to keep the ball.*
6-10 shots, the team is probably standing to the opponent, but is being inferior and is being dominated and had. A likely loss unless it's a poor match by both teams.
11-15 shots, the team is being able to do the job, though with no big displays. Probably a good evenly matched game. If it's a superior team, then probably has been building carefully the chances and will likely win by a small scoreline, like 1-0.
15-20 shots, the team is dominating the match, probably creating chances and unless the opposition is strong will be likely a comfortable win a 3-0.
21+ shots, the team is being too hasty, the players are too impatient to score, they shoot too soon, either because they're so complacent they don't even bother to work a quality shot or *the opposition is playing a defensive strategy set to frustrate the players, making them shoot as soon they see a line out of desperation. Unless your goalkeeper is a real professional who stays at all times concentrated, it's likely one of the few chances goes into the net, besides, and probably their tactic will be geared so the few chances will be counterattacks when the team hasn't yet got the time to stablish the defence.

Barcelona - Sevilla. Javi Varas.
P.S. - First, it's questionable that what the AI determines as CCC is actually an easy chance. On a curious note, I use to win scoring the non-CCC. I think around half my goals aren't CCCs. But never got to annotate when it was and when it wasn't, so ti can be a 25% or a 75%.
