Non-Indian people/team being treated differently

I don't know if I'm overthinking or not, but I need a sanity check. A couple of months ago, our department underwent a huge change. Our department at 400+ people and close to ~25 of those were working in US and UK. We had layoffs in may. A month prior to that, those 25 people were shifted to some other department with no changes in their roles despite us being told that our roles were pretty much obsolete and we'll be shifted and trained to take up other similarly structured roles. It's just crazy because there were no layoffs only for those people but almost every other department in all countries had some people laid off. This question of mine wasn't answered when I asked in our leadership office hours. It's crazy because usually Indians are cheaper right? It was not like those 25 people were generating a crazy impact that other Indians weren't. Anyway, a lot of us like me are now stuck in a different role and are being trained for something that would provide absolutely NO VALUE once we are out of this organisation. Have no motivation left and conspiring is what I do to spend my time during those trainings as I don't see them providing value at all.
