When a guy says “it’s all good” ?

I had apologized to a guy and congratulated him and he responded “thanks and it’s all good” what does it mean for a guy to say that. Is it sarcasm or? He also still doesn’t talk to me even after I apologized 😔

he's not not my boyfriend also

I told him that I truly do apologize for what I said and I miss talking to you. I congratulated him on his stuff and said maybe we can rekindle our friendship. He said “thanks and it’s all good”
