Randowhale doesn't make your post more or less likely to be seen. It's not a magic account.
If you have content that other people like, and you're interacting in the community, you will get more exposure. There's no secret trick to getting popular or rich here.
Randowhale knocks your post's worth up, and this increases visibility, unless your post got omitted by Steemit's display mechanism due to not having a link to a pic or a vid.
If Steemit omitted your content from searches, people will not be exposed to it, and obviously will not get to like it, so exposure comes before liking.
Likes do increase exposure, but likes can not happen without exposure, while exposure can happen without likes.
