Unfortunately, it's also BS from start to finish (heh heh). People still care about their own lives, even if they realize that it's useful to appear unreservedly dedicated to the customer's needs.
And the niche you choose does make quite a difference in what the resulting business will look like, what demands it makes on your time, what kinds of customers and partners you will be interacting with, etc..
Unfortunately, if you're looking for "a niche, any niche" that happens to meet criteria completely unrelated to what the need actually is, who the people actually are, etc., it seems unlikely to work out well.
I suppose this depends on personality, but... it's hard to build a business. If you find the perfect niche but you actually have no past domain experience, don't have any personal connection to the "pain" you're fixing, etc., what will carry you through? I imagine you'd be much more likely to throw in the towel when things got tough (and I suspect investors would worry about that as well).
