Countless pages similar to the main page of the site

Hi
I have a major problem with WordPress. Thank you for helping me solve this.
I have launched 2 websites for myself at the following addresses:
​https://virgoolshop.com
​https://coolyadak.com
Unfortunately, the home page of the site has countless copy pages. For example:

​https://virgoolshop.com/page/2345
​https://coolyadak.com/page/2345

I searched a lot to solve this problem but I did not find an answer. I will be happy if you guide me in solving this problem.
In addition, for the first website I mentioned above, I paid a programmer to solve this problem.The templates are different and the problem seems to be from the core of WordPress.
You put the end number in any number, the site comes up
