Rating and probability of win-draw-lost



A better approximation of the chance of drawing can be found here: https://chess-db.com/public/research/draw_rate.html Keeping the rating difference fixed it tends to increase with player elo. Similarly for wins and losses.
Dear chesslovers,
I never take ratings seriously but these questions do bug me for some reason:
1) Suppose I am rated 1000 and my opponent 1100. What is the "expected win"? Or draw in this case?
2) If my opponent is rated 1200. What is the expected win and draw?
3) Now if I am rated 2600 and my opponent 2700. Is the expected win or draw the same as in case 1? Is the rating system bias towards the high end? Would a 2700 find it harder to beat the 2600 than a 1100 would to a 1000?
4) Is there a formula to calculate the expected draw? I have the formula for ratings calculation but how do you convert that to calculate probability? Sorry I am from the arts stream. I love maths but took business subjects instead.
Thank you in advance for helping me.
