The other kids' parents generally have the same top priority and it's not to see the team win. The top priority is to see their kid play.
When your child puts in countless hours at practice, it's only normal to hope their hard work translates to playing time and individual success. It can be especially frustrating if the team is winning and parents are still complaining about personnel decisions. The sooner you can understand this the easier your journey will be. End of rant.
