Answered Prayer - Part 1/2

As believer, we are told when we pray, 3 things can happen.
God could reply "Yes", God could reply "No", or God could reply Wait".

As believer, at times, we also say or hear others say
"God answered my prayer." or "God did not answer my prayer."

But aren't all the 3 replies considered "answers" from God. So didn't God answer prayer in either "Yes", "No", Or "Wait."

So what are we really saying when we say "God answered my prayer." or "God did not answer my prayer."
