Current state of characters in Dragon Ball? I watched Dragon Ball, DBZ, DBGT, DB Super, but the order is such that DBGT is in the end I believe.

What happened to all the characters? On dragon Ball wikia, it said Goku died and is dead right now at Age 801, but I never saw this?
Dragon Ball GT is non-canon, when you say Goku died is because he turn the guardian of the Dragon Balls (you can watchDragon Ball GT: A Hero's Legacy to see that is true), but it doesn't matter because is not official, the official series is Dragon Ball Super.
