Any private key which produces a public key, which when hashed with SHA-256 then RIPEMD-160 produces the above number, would be able to spend coins at that address.

I didn't say the opposite. I said it may. It may also have none, it's just extremely unlikely.

Minor correction: If you have 4 possibilities for one character in a 64 character private key, then the total number of possibilities is 2²⁵⁴. If you knew for certain one character in the key, then you would have 2²⁵² possibilities.

Why do you have 4 possibilities for one character? Isn't it 16? (0-F). I don't get this.

Actually this needs a correction:

(for every hex character you remove you have 2⁴ times less combinations)
