Lets see, if we did that with a person, they'd be 42,000 feet tall. I suppose if someone made an animation of that, you'd conclude that humans are taller than Mount Everest.
the "The surface in the video is the geoid amplified by a factor 7,000" had already been mis-cited by you and was unnecessary to the point.
While you are fixated on surface features, the issue is the actual shape NOT being spherical.
while i can agree that surface features, such as Mt Everest, would not be easily detected from "arm's length", it is misleading to assume the shape of a cue ball.
More revealing is that the text i did quote was conveniently omitted from your posting....and obviously overlooked by you.

Mt. Everest is just under 9000 meters. 100 meters represents about 1% of the height of Mt. Everest. In addition, because gravity would pull the water down at Mt. Everest relative to other places on the earth, it will take MORE water to cover the highest point than if you ignored the gravitational effects.
weird...gravity actually weakens with altitude...people (and water) weigh about 0.28% less on top of Everest than at sea level....in other words gravity pulls water "down" at sea level with greater force than at the top of Everest. This is also impacted by the change in air density...but what you are saying finally explains why people in orbit are always so heavy.
You have also, conveniently, ignored the proposition by science that the earth has been expanding over time.
Thank you for playing.

which seemingly equates to the size of your grasp on the topic.
Local variations in topography (or bumps on the orange)cause fluctuations in the Earth's gravitational field, known as gravitational anomalies. Some of these anomalies can be very extensive and can result in bulges in sea level.
which, being just bumps on an orange, enables water to behave in very different ways across the surface...shallow and deep not solely due to its "bottom".
in other words...the flooding would not have to be concentric to your imaginary sphere....water would not have to be of a uniform "altitude" (ie top of Everest across entire planet) in order to cover the earth.
again, thanks for playing
