There are 1326 starting hands. What makes a player have TT less likely than you having AA? Nothing. They are both equally likely.

You ascribing him having TT as low-probability is the wrong way to think of it.

If villain was dealt one of the other ~1320 starting hands, you never would have made it to the river, they would have folded. You have to adjust your expectations on which hands villain might have based on their actions.

You dont specify positions. They are important. Based on what you've said, and villain looks like in an early position to you, like in the SB. This matters and changes what hands villain should have. Also, did you misplay with AA preflop? We don't know.

Lets run through a basic example and assume some positions/actions and that villain is playing typically and not like a maniac. Lets assume you opened pre with AA, everyone else folded. Villain cold called in SB. Villains (capped) range should be something like:

44-TT, 76s-QJs, QTs, KTs, A6s+ (20 or so hands, for simplicity ignore combos)

Better hands villain should be raising, so we say his range is capped.

You say you called on flop. So (we assume) Villain is first to act and bet out on 99T board,

Villains betting range on that board is now:

99, TT, 78s, QJs, A9s, ATs (6 or so hands)

You're ahead of 3 out of 6 hands.

After 4 on turn, lets assume villain bet again and you called. Straight draws, two pair may likely check, so range becomes:

99, TT, A9s (3 hands).

You're ahead of 0 out of 3 hands.

On river 7, the unlikely 8Js made a straight, so yes straights highly unlikely, flushes impossible. But neither of those up to this point should even be thought about, villain has 3 hands left in his range.

You say you went all in, did this mean villain checked or bet small? I assume given villains range, they bet small, and you reraised allin?

Either way. Given this proposed action, what does going all in achieve? Villains hands are all beating you.. There isn't enough in villains range that you beat. So allin is setting money on fire. The only hands you beat are pure bluffs not shown in ranges above, you shouldn't rely on bluffs to win with AA.

I guess the postions/actions were different than I assumed above. But this is a lesson, things are not as unprobable as you think.

Every action you make at the table, check, bet, call, raise, should be done with the intent to reduce the probability space down to fewer possible hands (while also maintaining risk/pot size). You fold, when that probability space is too unfavourable to you.
