    If you are only referring to WordPress updates then no it will not change your theme or plugins. Theme and plugins are updated separately and manually. When updating WordPress, it overwrite all core files and folder except wp-content.

    Yes. Your changes in theme will only flush on updating your theme.

Yes, theme update will overwrite its folder completely. If you are using third party theme with possibility of updates the normal practice is to put your customizations into a Child Theme for it.
