I am using Thrive Content Builder will changing theme affect the contents

My name is Fahad, and I am new to WordPress,
Recently I migrated my blog from Blogger to WordPress, and I used the Thrive theme and their content builder plugin to create amazing contents.
But the problem is now I want to change the theme of my Blog with a theme that is available on ThemeForest I have built the Payoneer Sing Up and earn 25 Dollars page using Thrive content builder.
And I have to spend a lot of time in creating such page using Thrive content builder, and I don’t want to do this again.
Please let me know if this is possible to change the theme without losing my work.

Ask the author of the theme https://themeforest.net/item/thrive-intranet-community-wordpress-theme/12275020/support
