From what I know about Arman Tsarukyan he is from a rather wealthy family and lives a well lavished lifestyle.
So when someone says that they paid him money to do something, I tend to question the source. And from what you had just stated, I would definitely do the same.
The guy doesn't need to fight for the same reasons that most in the organization have to and rely on fighting two or even three times a year.
From the sounds of it, Arman wants the easiest way to a title as possible and if it isn't on his terms he won't do it. That is all I can really say about this fighter and his current situation of trying to find a fight.
I didn't know about his family's wealth. But I believe the path he's taking isn't the best. The organization needs to earn something too, and having a champion the easy way would be frowned upon by the public and the fighters themselves. It would take away all the fighters' merit. So, the fewer fights he has, the worse it will be, which is why he hasn't achieved anything significant.
