On Nostr, people send their note to relays, which hold them together in a big library. When you follow people, you ask the relays to send you the notes authored by the people you follow.
How much engagement in zaps or likes or comments or boosts a note has makes no difference in that process. But you can discover other people based on boosts other people make.
There may be clients in the future that allow for different algorithms besides seeing everyone you follow in reverse chronological order. But it will always be your choice hope you want your content displayed.
