I understand that boiling water with salt in it, you end up with just salt. But, How does it work with two liquids? Wouldn’t they just mix and end up with the same boiling point?

No.
When you mix alcohol and water, as you warm the solution the alcohol evaporates first. If you carefully control the temperature and cool the gas released into a different container, you can separate the alcohol in a new flask while leaving the water in the initial container – just like the salt.
If you do this while raising the temperature, you boil the alcohol and the water, leaving the initial flash empty and the second flask with the same mixture. That’s just not doing distillation by fraction correctly.
