This page https://wage.is/marshall-islands/ claims the average is US$168000 per year and the median US$9600 per year. [My guess is that the poverty line is close to US$5000 per year, probably higher.] This program adds US$800 per year. So it's a "universal partial basic income" instead of a "universal total basic income".

In all the discussion I remember, "universal basic income" == "universal total basic income" but perhaps I was not paying too much attention.
