Figs are pollinated by fig wasps that die in the fruit. So I think figs are a pretty unique case and not indicative of something you have to worry about in most other fruit
There are 855 species of figs and almost every single one of them has a corresponding species of fig wasp that pollinates only that fig
"Most are not" only applies to figs you buy at the grocery store that are a variety of the Ficus carica species. This variety is sometimes able to fruit without pollination (sometimes requiring application of a fruiting hormone).
But the vast majority of figs are not the common fig and not this specific variety of the common fig
