While following a lot of people can populate your Home feed significantly, sometimes people (like me) end up boosting a lot and that can unexpectedly hinder your own experience.
So if you like someone's specific posts and don't want to follow their boosts, you can go to their profile under the [...] button, and select the "Hide boosts from account" button.
There is no algorithm on Mastodon. You have ownership and control over every filtering decision instead of some robot.
