There’s a lot of different lists out there based on different past tests, official practice material, and textbooks for learners.
If I’m not mistaken N5 itself was made just looking at what beginner books taught you.
Knowing a few N4 words at N5 doesn’t hurt. It’s a step towards being higher than N5 and there’s no guarantee you won’t see them at the test anyways since they do use words past expectations here and there.
If you are in dire need of N5 asap to be admitted to a specific language learning school I understand wanting to focus on that, but if you’re in no rush and your longer term goal is just “become conversational, be able to watch anime, read manga” then don’t worry about it at all. A lot of the most common words are “N1” or not even in the JLPT levels at all.
俺 is marked N1 which is one of the most common pronouns and the 444th most common word in the jpdb media occurency list. You wouldn’t wait until you’d learned many thousands of words before learning this if your goal is to learn Japanese.
Don’t worry about it, 並ぶ is very useful and one of the 1000th most used words so you can just learn it now.
