UX is the overall impression a user would have when visiting your website. Do they understand what your website is trying to do? Can they figure out how to navigate it? Is logging in and purchasing an item an intuitive process? Visualize walking into a corner store on a Tuesday morning, pouring a cup of hi-powered coffee, grabbing a pack of gum and heading to the counter to pay. When you get there, the person says that you have to pay for your items in the bathroom and that they only take payment in quarters from 1997. This would be an example of a bad user experience. You can still get what you want, but you probably won’t get anything.
