When a caddy says "140m after accounting for the downhill slope," does that mean I should hit it 140m?

Even though I've been playing golf for quite a while, I've always found this a bit confusing, but I've never actually asked anyone;
On a downhill Par 3, for example, when a caddy calls out the distance, they often say something like, "It's 140m after accounting for the downhill slope."
Usually, when playing on a simulator, we calculate the distance by adding or subtracting the elevation change.
In other words, if the distance is 150m and there is a 10m downhill slope, it's calculated as 140m.
So, saying "140m after accounting for the downhill slope" means that the final calculated value is 140m, so I should aim for 140m, right?
