There are 2^256 - 2^32 - 2^9 - 2^8 - 2^7 - 2^6 - 2^4 - 1 private keys
Hahaha, "a LOT fewer", you're kidding right?
It's 0.00000000000000000000000000000000000000000000000000000000000000000037% fewer. That's not a LOT by any stretch of the imagination.
And it's still more than there are particles in the universe, and a LOT more than we can even theoretically
count (let alone convert to an address and probe for bitcoin balance) if we could use all the energy in the sun at the most efficient, optimal (in terms of thermodynamic limits) way.

So, no sir, 2^256 minus an insignificant percentage is way, WAY more than enough.
