Answers

It can take off and land on a short runway under certain circumstances, so you can stop it in 4,500' on a wet runway at maximum landing weight. But operators don't like to max out reverse thrust and brakes because it causes expensive and unnecessary wear.

Fully laden at sea level the required runway length is 10,400 feet. At 360,000 pounds, 70 tons light of max, the aircraft needs 5,000 feet to take off. At MTOW it needs over 9,000 feet.

So all in all, not really for practical commercial operations. The 787 needs as much runway as a 747 or an A380.

Is that surprising?

It depends on weights and density altitude.

Also, ground run and balanced field are two different things--just because it can takeoff within 5000' does not mean it can legally use a 5000' runway.
