If you follow your argument logically, it says there's nothing to do and we're in a good place.
You said we need to have 5.4tCO2/person/year on average across the world. You then presented a table that shows that we are in fact _under_ this target (4.7t). In your follow-up comment you claim that the lower-income countries are "never going to emit much more than they do now". So by your argument the world average will probably stay below the 5.4t goal and we're on target.

The target of 5.4tCO2/person/year is assuming we take a linear path down from 2023 emissions to zero emissions in 2050. It is the halfway point on that line.
Real world reductions (or increases) won't follow a linear path. Global population is also increasing. The number is just a rough estimate to show which countries are dropping the ball.

You're missing the core of the argument:
"If we assume that we get to net zero by 2050,"...
US+China+Europe+Australia have cumulatively emitted 70% of all historical emissions. They are still 3x the world average and the estimated target. That's why they are on the list.
China is there because it is a common villain in these discussion. The low-(middle)-income countries are, in my opinion, never going to emit much more than they do now. They will never contribute to the problem but will feel all the effects.
