@sakamvari saying the tile distribution is "randomly chosen" makes it seem as if you have not understood the original complaint. The letters that each player receives during the game may be random, but that isn't what the complaint is about. It's the actual number of letters in the basket (or the bag, or the pot, or whatever you call it: where all the letters come from). Proportionally it seems as if the game always has too many I's. (apologies if I have misunderstood the complaint myself!)
You did not misunderstand what was said.
