the only number you have to worry about is the estimated earning. that the one you get.. so if you made 15$ in that month then yes, rpm will take 50% or 40% depends on your contract... but they have a thershold of 50$ now. so if you havent made 50$ then you have to wait another month until you reach the thershold.. and socialblade is just an estimated, remeber that they dont count the views that are not monetizables thats why they have more than normal.
