the.com/numbers game

means A strategy or activity whose success depends on probability and sheer volume of attempts rather than precision — play enough odds and some will land.

from The phrase borrows directly from 'numbers racket,' the old illegal street lottery (big in American cities through the early-to-mid 1900s) where bettors picked numbers and payout odds were stacked hard in the house's favor. From there 'numbers game' widened into general use for anything — sales, dating, gambling, even bureaucracy — where outcomes are really just the cold arithmetic of probability and volume, dressed up to look like skill or choice.
