Steem power the real power on steemit??

I'm still new to this network but after seeing many posts and videos on d tube i've realised that steem power is what decides whether a person gets rewarded or not, for example i have seen posts with about 200 upvotes and still having made 58.6 dollars and on the other hand i have seen posts with 14 upvotes and having made about 78 dollars and when i saw the upvoters i saw a person with about 3000 steem power which was the reason for the post getting that highly rewarded .
