Poker Help with equity

So I'm trying to analyze a spot where I busted a tourney earlier. In the hand I get it in 99 vs AQo and at first I thought my play was the correct one, but when I plug my hand vs range of hands villain will call my jam with I am an underdog. Does this mean my play was bad? I'm unsure of how to factor fold equity in here. Is there some formula for taking hands that would 3bet but fold to a jam and apply it to the equity I have here? I'm really trying to improve. This is like the 10th tourney I have busted this week with under 20 people left but short of the final table and it's leading me to 2nd guess some of the plays I'm making. 3-4 table sit and goes are my bread and butter and fund all tourney buy-ins I make. So when I make it this far to not even make the final table...like I said I'm 2nd guessing. What other factors apply to equity here that I might overlook. I'm very new to using an equity calculator. Thanks in advance.
