Does it mean I should use up the last 10% and then get my oil changed otherwise I would just be throwing money out the window (the last 10% of use)? Or does it mean get the oil changed right now because my oil is gross.

A car has within it no sensor that can measure oil quality, you need a lab to do that
Therefore it’s either measuring hours, or miles. When the oil gets changed, someone resets that clock, and it counts down. The timer means nothing, it’s arbitrary, and likely a sales tactic to get you back into the dealership – their objective is to make money.
Say they set 10,000 hours, 10% oil life would then mean 1000 hours of oil life left. But that itself means nothing
You’re not at 10% quantity of oil remaining. your oil isn’t 10% as good as it was at the beginning… but it is deliberately phrased that way to get you to open your wallet. Ignore it, and buy a car that doesn’t crowd your screen/clocks with that kind of bollocks in the future
