Why some seeds are used for oil extraction and not all

Question

From my understanding, oil in seed is fat reserve to be used in initial phase of germination. If thats the case why all the seeds don’t have oil.

Answer 1

All seeds have *some* oil but we use the ones with higher oil content because it’s more economical (more oil and less wste from pressing a given weight of seeds). The ones with less oil, or whose oil tastes bad, don’t get used because there’s better options.
