Hello! 1. "I got to talk about the party." - It means that you got the chance/opportunity to talk about your experience (the party).

"You got to have a party. I baked." - The meaning here is basically that you have to organise/throw the party since someone baked for you (e.g. a cake). Hope it is understandable&helpful! :) Have a good day!

1) I had the opportunity of talking about the party. 2) You were able to have a party. Unless this is 'colloquial' and in fact the 'correct' version should be "I have got to...", In which case the meaning changes to 'must'. You would really need to hear this spoken in context to be sure...🤔🤔

They have different meanings. 1. I managed to/had the opportunity to/could/was able to talk about the party. 2. You must/have to/really have to/really must have a party. No worries :)
