The word is a simple compound of 'der Sieg' (victory) and 'der Treffer' (hit, goal, score). So it is literally the score that brings victory.
EXAMPLE

Everyone was waiting for the decisive winning goal.
Typical verb
By far the most common verb used with 'Siegtreffer' (winning goal) is 'erzielen' (to score). 'Schießen' (to shoot/score, in football) or 'werfen' (to throw/score, in basketball) are also possible.
EXAMPLE

The striker scored the winning goal shortly before the end.

EXAMPLE

Siegtreffer vs Treffer
hit
'der Treffer' and 'der Siegtreffer' can both mean a goal or point in sports. 'Treffer' is general and only says that someone successfully hit the target or scored. 'Siegtreffer' is more specific: this goal or point decides the game or secures the victory in the end. The words can be confused because a 'Siegtreffer' is always also a 'Treffer'. But a goal at the beginning, or a goal without a decisive effect, is not a 'Siegtreffer'. If you want to emphasize its decisive importance for the victory, use 'Siegtreffer'.
Siegtreffer
In der letzten Minute erzielte Ali den Siegtreffer für seine Mannschaft.
In the last minute, Ali scored the winning goal for his team.
Treffer
Nach dem Treffer stand es 1:1, und beide Teams spielten vorsichtiger.
After the goal, the score was 1-1, and both teams played more cautiously.
