could+have+pp

Hi;

To express past probability, to say that we missed out on an apporotunity in past ; is it correct to use 'could+have+pp"

“I could have gone to college when I was younger.”[b][i]regret over a missed opportunity

“The Smiths could have lost their way.” [/b]past probability

Is it correct?
