からある・
These forms present a stated quantity as a surprisingly large lower bound: “at least that much” or “as many as that.” The actual amount may be higher.
A large threshold, not an exact total
The number before からある, からいる, からする, or からの is a threshold. The speaker is saying that the amount reaches at least that level and presenting that level as remarkable. Do not translate it as an exact total unless the surrounding context independently establishes one.
The four core patterns
