Class of 21 decisions

So i sent in my application to UBC before the deadline, but I’m still to send my anticipated grades and transcripts to them. Although, I have a friend who sent in his application on the same day as I did, but sent his transcripts and all required documents 3-4 weeks ago, somewhere in the last week of jan I think, and he already got his acceptance letter

Is it reducing my odds of getting in that I’m sending my documents this late? (I’ll be mailing it to them in 2-3 days)
Also, the deadline for sending documents is march 15th, what if my documents reach them later than that because of the large number of documents they receive and process?
