You're mostly correct, but hilariously even all that wouldn't be good enough because water behaves differently at different scales. Surface tension would dominate in a miniature model, and the water would be trying to stick to everything in a way which oceans simply don't do
I did think about that, but I don't know how surface tension works. I'll certainly take mostly correct. Not bad for an amateur who just watches physics videos for fun.
You may not be a scientist, but your summary is pretty much spot-on. And it certainly makes a hell of a lot more sense than whatever horse shit the flat earth clowns are pushing.
