1. If i control Blood Artist and 3 token, then my opponent cast Fumigate , My blood artist will trigger 4 times
2. If i control The Gitrog Monster , and my opponent cast Decimate targeting my Gitrog and my land, the gitrog last ability won't trigger
Based on CR
700.4. The term dies means “is put into a graveyard from the battlefield.”
the only difference that i found between "is put into a graveyard from the battlefield" and "put into your graveyard from anywhere" is that the second one can be from anywhere
can someone explain me why the first scenario trigger 4 times but the second scenario didn't trigger at all?
Decimate does not destroy its targets simultaneously. It destroys the artifact, then the enchantment, then the creature, then the land. The land goes after the monster, so the monster does not trigger. Fumigate, in contrast, kills all creatures at once.
The difference isn't between "dies" and "put into the graveyard". As you noted, "dies" just means "put into the graveyard from the battlefield". The difference is that Gitrog says "put into the graveyard from anywhere". The "from anywhere" is key here as it changes how the ability triggers.
When dealing with "dies" or "put into the graveyard from the battlefield" triggers, we look back in time to see if anything should trigger. This is because if we didn't, dies triggers wouldn't work since the ability only works from the battlefield and the card is now in the graveyard. So, with Blood Artist, we see 4 creatures dying. We then look back to how everything looked on the battlefield, see that Blood Artist has a trigger that should trigger in this case, and then those triggers are put onto the stack.
Gitrog, on the the other hand, triggers *after* things go to the graveyard. So, you discard a land and Gitrog says "I saw that; here is a card". However, if he dies at the same time as a land is destroyed, the game looks at the game state after the land goes to the graveyard. It does not see anything that should trigger (since Gitrog is no longer on the battlefield) so nothing happens.
EDIT: Technically "dies" is a "leaves-the-battlefiled" trigger which is what looks back in time. This is relevant for things like Thragtusk as hey don't have to die to work but the triggers work the same way. Gitrog is never a leaves-the-battlefield trigger even if the card comes from the battlefield.

This isn't true. For each action word ("destroy" in this case) everything is done at once. Since Decimate says "destroy" once, everything is destroyed at the same time. Following the order on cards is for things like Smallpox where you do things in a set order. In that case, you could discard a land to get Gitrog to trigger, but then he is gone by the time you sac a land.
