How to point single page with dynamic url in WordPress

Question

I have the below use case.

• I have a list of $states: ['Alaska, 'Virginia', 'California'] so once the user type state in the URL ex: xyz.com/virgina then after extracting the state from the URL I have to point to one page only that I have created from WordPress Admin default page URL is xyz.com/page-1

Thanks In Advance

I have tried with wp_redirect() function but it's redirecting to specific page and changing the URL as well but URL should not change.
