With copper low, that means you are probably just wearing down the top lead layer of the bearing.
I would say no need to be alarmed, but it shows your bearings are wearing and imo I would be planning to do a rod bearing change in the future.
In terms of how long you have, no one can know for sure, a bearing could starve for oil for a couple of seconds, then spin the bearing causing rod knock or shoot a rod out of the block depending on how bad it is. or it can continue to run fine for another 50-100k assuming the wear doesn't continue at the same rate, if it does continue at the same rate then you probably have much less time.
