I come across this term Weighted a couple of times. Its on Flopzilla and I've ran across it in SSNLH. What is weighted in the poker world?

Let's say someone 3bets, and you think their range is:

AJs+, TT+, 54s+

More weight goes towards AJs+, TT+, and less weight goes to 54s+, meaning 54s+ is part of their range but they don't do it with those hands as much as the latter

Like tens said . A more extreme example . A guy only 3 bets AA and small suited connectors . His range is weighted to small connectors when he 3 bets because thats the most likely hand that he will be dealt .
