I checked the winner list of the Codeforces Round 729 (Div. 2) for motivation and how much they practiced to get the top rank. I noticed something peculiar about the winning accounts that almost none of them have given more than 10 contests. Then I checked some past Div 2 winners and it is almost the same in every contest eg Codeforces Round 728 (Div. 2) and Codeforces Round 721 (Div. 2). Then I check some top-rated coders and even they started with the almost 1-2k standing/ranking. Why do you think that now the newcomers to CP are this good from the very start? or is it just my confirmation biases?

P.S: I don't want to tag the people I'm talking about as it may waste their time. You can check the winners from contest announcements if you want.
