No, as I wrote at the other post, it's not coincidence.
First, that 1000 liters are a cubic meter is no coincidence because that's exactly how the liter is defined. Second, that a liter of water has the mass of 1 kilogram is no coincidence because that's how the kilogram was originally defined.

yes your quite right i was thinking of it backwards the litre the kg are relatively arbitrary in that a kilogram and litre of water would be a bit bigger if the meter was.
but apart from the meter seems that water gets used for part of the definition a lot.

lucky coincidence that 1000 litres = 1000kg of water and that happens to be pretty close to being 1 cubic meter at room temperature.
There's no real reason why they have to be so close, I guess gravity could be a part of it.
