Yes. Adults teach children what matters through their reactions, even when nobody says it explicitly.
If every goal gets the biggest noise and everything else gets a polite clap, children quickly learn that scoring is the action that earns attention.
I would not make goals less enjoyable. Celebrate them. But start noticing other things with the same energy: a recovery run, a brave attempt to receive, a teammate helping after a mistake, a defender delaying a 2v1.
You can even tell parents before a game what the group is working on and ask them to watch for it.
The nice thing is that praise becomes more individual. The child who rarely scores can still leave knowing something they did mattered.
At U8, that broadens the idea of success without removing the excitement of putting the ball in the net.
