Is Magi - the labyrinth of Magic the continuation of the Netflix series Magi: Adventure of Sindbad?

The above is actually the whole question.

Magi the labyrinth of magic is the real anime. Magi: Adventure of Sinbad is just the story of a character of Magi the labyrinth of Magic ^ - ^

No. Sindbad is an alternative story with a focus on Sinbad. Magi - Labyrinth of Magic follows another story

No.

Magi: The Labyrinth of Magic (S1) and Magi: The Kingdom of Magic (S2) are the original series. Sindbad is a spin-off series of which Sinbad is the focus of the story. In the Magi series he is only a secondary character.
