the page/2 etc. URLs are pagination links automatically generated by WordPress for the archive pages.
The URL parameters are created by Views to manage pagination in the context of any other filters or customisations that may be applied to the query.
A theme would typically output standard pagination links, which don't take account of any customisation of the archive query, and which are determined by the setting at Settings > Reading > Blog pages show at most. If you don't want to generate these automatic pagination links you could set this to a high number, e.g. 999, and it will apply to all post archives, so that such links are not generated and any pagination comes solely from Views.
You could use the standard pagination links and not add pagination from Views, but you would have to edit the theme files to control where you wanted to display them, and they also wouldn't work if you added any custom search or query filters to a View or custom archive.
