This does not prove anything toward a flat earth. The earth is so large, that many places on it are uneven. Putting a level to the ground does not bring up a conclusion that the earth is flat. If you had a super long pole that is perfectly balanced, and put it on the ground, (assuming gravity does not bend it) the pole would eventually lift off the ground at a very small angle, and head out into space.
Is anyone who says people are brainwashed actually educated? We are taught plain facts like a round earth in school for a reason. If you gone to school, you would be able to see that.
