Can Someone With Experience Answer This Because Im Hella Confused

[186]

Okay, so when people use dork searcher to find urls and use sqli dumper to find vulnerable websites derived from those URLs, how are people able to use injection attacks to specific databases like yahoo, or southwest airlines for instance. Do this sites have vulnerablilities? Does every site have vulnerabilities?, Im relatively new to creating my own combos, and I only seem to get 2 injectable links, and it always turns out to be some random asian website, and I just get stumped. How are people able to get databases like yahoo or aol and be able to dump combos from them? Are there better tools to do so, since ive been using SQLI Dumper 19.3, and Dork Searcher V3. I would really appreciate the help on this, thank you.
