A year ago, Google was doling out results at a rate of 34,000 searches per SECOND. In your case, that's filtering and spreading your ad across some 3.4 million searches. Not unreasonable to assume your demographic restrictions fit about 1% of those searches; the limits sound narrow, yet seem candidates for the largest group of Google power users (whom I would independently assume are dominated by 25-45yo upper-economic-half US state residents owning camera-laden iOS devices).

You're trying to take a drink from Niagara Falls and wondering why you're soaked. (Been there, done that. Memorable, but not productive.)
