From what I have read and people I've spoken with, the games industry definitely uses Blender the most out of Games, VFX/Anim, and ArchViz. But the latter two, not so much out of isolated pockets, and usually nothing past the modeling phase. I'm coming from the studio VFX/Anim side, so I'm biased in that regards to my viewpoint in adoption.
Blender isn't THE industry standard by any means, but I don't think it would be a stretch to call it an industry standard. EA uses it for a lot of their concept work, Ubisoft uses it for their animation studio, it's the modelling tool at Infinity Ward, etc.
