What it means
からある follows a quantity expression to emphasize that the amount is surprisingly large, often conveying “as much as” or “as many as.” It commonly modifies a following noun, especially in formal, written, or descriptive language, and presents the stated quantity as a substantial minimum rather than an exact upper limit.
Usage note
からある should not be confused with the ordinary particle から meaning “from.” It is most natural with measurable quantities such as page counts, distances, weights, sums of money, and numbers of people or items.
