The difference between top goalscorer and golden boot winner

There could be multiple top goal scorers, but there can only be one Golden Boot winner. Multiple players could score the most amount of goals, but only one will be awarded the Golden Boot. If there is a tie, the player who has the most number of assists will be awarded the Golden Boot. If there is still a tie, then the player who has played the least amount of time will be awarded the trophy.

In all short tournaments like WC, Copa or Euro, Godenboot prize is handed to the player who scored most goals in that tournament regardless his form, performance or number of games played. Hence Goldenboot = topscorer no difference.

Since WC82, FIFA introduced another award - GoldenBall to pinpoint the best performer in the tourney and to differentiate with the existing Goldenboot (or just Topscorer)
