Google accounts for these sort of "boilerplate" content blocks.
In this case you're talking about like a Call to Action statement.
You're totally fine, it's not going to hurt you. These are very normal sections for pages to contain after the primary body content is finished.
What would be duplicate content?
If you copy and pasted content from another website and sort of reworded it a little, and tried to claim that your page as the canonical - that would be dinged as duplicate content.
Sometimes it makes a lot of sense to duplicate certain content from your site, like reviews, across pages. 3rd party content such as passages from Wikipedia pages get duplicated all of the time - the reason it's not duplicate content is because it's supplementing the primary content.
A great example is like on this site - we duplicate content all the time from other sites in answers when referencing documentation, guidelines, or passages that corroborate claims. But it's not like it makes up our whole answer.
When Google seriously penalizes sites for duplicate content, it's typically because the site is overtly trying to cheat. Like plagiarism.
