how above sea level high could a navigable river go? could it remain navigable up to 1000m if its long enough?

do you mean a height of 1000 meters?
There are examples up to 650 meters, so 1000 meters is possible.
The Saint Joe River, Idaho: With a mouth elevation of 2,129 feet (648.9 m), it is the highest navigable river in the world.

Water in a river is essentially horizontal.
Ships can not navigate past rapids or waterfalls.
Of course rapids and waterfalls can be passed by a lock system - which raises a ship from a low to a higher portion of a river.

My study of rivers is that they remain flat along their course except for the waterfalls. Going towards the sea(downhill) the last waterfall signifies the beginning of the estuary.
