Not to everyone. Neither do all of the pages that you've liked over the years show up in your news feed.
Basically, the procedure is the following:
post is shown to a small minority
while a proportion of the people seeing it engages with your content:
show the content to more people
So, if the initial... let's say 200 people that see the post on your Facebook page are not engaging with it, the content wouldn't be spread further among people who liked your page. If they engage with it, the content will be spread further.
That small minority decides the future of your post. If you have non-genuine likes that are not interested in your content at all (as in, not engaging with it), but they see the post first, you're gonna have to spend money to promote posts.
