If you send Bitcoin to the address derived from this invalid private key (1NLqpZnW746xjdAgnrTb56V4uZJiV4jjrU), the funds will be associated with that address. However, since the private key is not valid, you won't be able to sign transactions to spend or transfer those funds. In essence, the funds sent to that address would be irrecoverable.
Am I right?
That string you listed is an address, not a private key. And also, it is not an invalid private key. Even if the hex number is out of range it is converted into a valid private key by using modulo, as others here have pointed out (unless the number is 0 or a multiple of n). So no. Anybody will be able to retrieve any bitcoins sent to this address.
