Locks function using pins. You have to use the pick to set each pin individually, and during the entire process you risk slipping and allowing all of the pins to reset to their original locations. More pins make the entire process harder. In addition, I think some locks have mechanisms that can trick you into thinking you’ve set a pin correctly when you haven’t.
Asking if you can make an unpickable lock isn’t a question that can be answered with deductive reasoning; instead, you would need to construct an example of an unpickable lock to prove it was possible, and to prove your lock was unpickable, you would need to try an exhaustive list of picking techniques (which is impossible.) So your second question cannot be answered.
