You have different kind of trophies, first type is basically attendance trophy for everyone who showed up, this is just to tell everyone you arent a loser eventhough you actually lost.
and then there are trophies for wining competitions, given to 1st, 2nd and 3rd place.
To win this trophy you have to beat competition, which means your have to practice very hard and very well, and it takes as long as it takes for you to become better than others.
I doubt they give loser trophies to adults, because adults should understand that they lost, should practice more and loser trophies are worthless actually.
Usually they are given to kiddies who get their feelings hurt and cry on their mommies skirts for not getting something shiny.
