It's likely that those electrolytics will be past their prime, and swapping them will make you feel more confident about the future. It's remarkable how much degradation you can fail to notice, if it happens slowly enough.

If you have space, you could consider replacing the electrolytics with plastic film type and not have the worry for the future.

You probably don't have any choice with non-polarised types, but ordinary electrolytics com in different temperature grades and different life expactancy ratings... the better ones simply have better seals to slow the egress of the water content and maybe a bit more goo in them.
