Guys, What does it mean if a guy says yeah for sure?

Anonymous
ok so I know that the phrase ‘yeah for sure’ might seem like I’m overthinking and I probably am but I really want to know what men actually mean when they say ‘yeah for sure’

i asked a guy to come over who I have been casually seeing. He couldn’t come over and I said hopefully another night and his response was ‘yeah for sure’

is he just saying that or does he mean like yeah definitely will come over another night?
