Poker is more nuanced than that. There are several reasons why 3-betting a particular hand might be slightly more profitable than flatting it.
Reasons for 3-betting include:
* You can get called by hands you dominate (i.e. you're value-raising).
* You can fold out hands that have significant equity (i.e. you're denying equity).
* You can get called by a hand that is currently winning (e.g. a pocket pair), but you make the best hand post-flop and get some value.
* By having some weaker hands in your 3-bet range, you "balance" your strategy, which increases the EV of your premium hands. (i.e. Villain has to call your breakeven-ish pre-flop "bluffs" at some frequency, and this makes QQ+/AK more profitable for you).
AJo in BB v CO is one of those hands that probably uses a mixed strat at equilibrium. It gets its EV in various ways. It's a profitable call AND (vs most players) it's a profitable 3-bet. I'd recommend 3-betting it vs LAGs w/ high fold to 3-bet numbers, but flatting vs nits and fish that have low PFR numbers. You don't want to bloat the pot OOP with "offsuit trouble hands" if villain doesn't fold to 3-bets, because it sucks to play hands like AJo OOP with low SPRs.
To be clear, if/when you 3-bet AJo 100bb deep in BBvCO, you'd much prefer it if villain folds pre. It's not the end of the world if you get called, but you'd rather pick up the dead money uncontested.
