Yes, with suitably questionable delegations, it is possible to run out of IPv6 quickly.
The bottom line (IMHO) is that IPv6 is NOT infinite and propagating that myth will lead to waste. That being said, the IPv6 space is MUCH larger than IPv4. Somewhere between 16 million and 17 billion times larger based on current standards by my math[1].

Ever noticed that fat /13 for a certain military network in the ARIN region!?
At least those /19 are justifyiable under the HD rules (XX million customers times a /48 and voila). A /13 though, very hard to justify...
Not every customer needs a /48. In fact most probably don't.
Whether they need it or not, it is common allocation/assignment practice. I agree that smaller (SOHO, for example) customers should get a /56 by default and a /48 on request, but, this is by no means a universal truth of current practice. Owen
