The reason you can only get 50 is probably that you're passing rvprop=content, which has stricter limits because content fetching is expensive.
That's true.
The account your bot uses needs to be given bot rights. I have no idea what the criteria for that are or what the procedure is for applying for them, that's a community thing. Accounts with bot rights also get the option of marking their edits as bot edits, which means they'll be hidden from Special:Recentchanges unless you click "Show bots".
Are bots priviledged in terms of how many revisions the can request with action=query at a time ? Compared to a normal user who hasn't logged in I mean.
