Can someone you have blocked on iPhone still receive your texts?

Basically, I blocked this guy a while back. Last night, I accidentally sent a text to him (he has the same name as my friend who I was actually trying to message). It's in blue and says delivered on my end, but will he ever receive it?

American wishful thinking but it does not work that way in reality

Yeah he'll receive it blocking a number only blocks calls not texts

Blocked means incoming. Of course he gets it, unless he blocked you as well.
