None of that makes anything waterproof. That starts outside the house, not inside.

LWO is right on. Nothing you do on the inside of block will ever keep the water out, because block is permeable.

Start by making sure your gutters and downspouts are clear, and drain well away from the foundation.

Next, make sure that the ground slopes away from the foundation all around the house.

If those fail, then exterior waterproofing (pitch and membrane) and footer drains routed to a sump is the way to go. It will require digging. It will be expensive. But it will give you a dry cellar.
