@mods Creator inactive and unresponsive to questions and meaning is completely unclear to me as to whether deplete means
1. exhaust or
2. reduce a little or
3. more than the planned trajectory to maintain probability of limiting warming to 1.5C or
4. more than the planned trajectory to maintain 50% probability of limiting warming to 1.5C or
5 something else

I suggest it is N/A'd.

What does deplete mean? As in exhaust? or does just a small reduction with lots remaining satisfy "deplete"?

How does this actually resolve? The usually quoted figure is for 50% chance but obviously the budget is significantly different (smaller) for 66% or higher chance of limiting warming to 1.5 °C with no overshoot.
