Does gravity still 'work' when scaled down?

Assuming these numbers are right:
Humans are 668 times bigger than ants and that the circumference of the earth is 40,075km
Then if we made planet with a circumference (and everything else) scaled down to make ants the same size as humans, a planet with a circumference of 72km. Would this planet have enough gravitational pull on the ants to keep them on (lets imagine that ants are just like humans and cant climb and stick onto stuff)?
And also would this planet be strong enough to keep 70% of its area covered with water using gravity? If not why?

a human is 20 million times bigger than an ant when talking about mass which is the property gravity is dependent on(as well as distance between two objects) To answer you question, in the middle of space with no other masses to interfere, any two masses will attract, no matter how small, so yes a tiny 'planet' could hold ants onto it or water on its surface.
