How do some posts get over 1K upvotes while other extremely useful once range between 50 and 200 upvotes?

The other day i was scrolling through the Top posts and for real though i have seen some totally random posts with 12 thousand upvotes that simply share a silly self story thats mildly humorous.

On the other hand ive seen other excellent DD and Research posts that are full of comments but stay in an upvote range of double or triple digits.

It really makes no sense to me. Dont get me wrong i lo e a good laugh and i will upvote if something made me laugh but sometimes im really confused.

Are bots involved or how does this happen. The upvote difference between 50 and 12 thousand is pretty large and considering we have millions of members its pretty bizzare to me.
