Thanos vs. Hulk takes place at some point during the original Marvel NOW!, as pointed out by the introduction page and by Thanos statement in, in which he reveals Adam Warlock not only absorbed his entire reality but its Living Tribunal too, and he was alive at the time it happened.

, Infinity Entity, and seemingly take place after Infinity and before the Black Vortex crossover.

Just Earth-616 was destroyed in the events shown there, and it was restored afterwards by the Above-All-Others. The events shown in Thanos: The Infinity Relativity, Infinity Entity, and Thanos: The Infinity Finale were simple wiped out from the timeline, in other words, the timeline was reset to the point before Annihilus started his invasion of the Posiverse, and what once happened was overwritten by what came next (Thanos defeating Annihilus, Adam Warlock becoming the new Living Tribunal, etc.).

It was never implied that the All-New, All-Different era was Thanos' doing, but that it couldn't have happened without him (just think about it, what could have become of the Multiverse if Earth-616 didn't make it to Secret Wars?). And Adam Warlock becoming the Living Tribunal apparently happens after the Secret Wars.
