IMO for the majority of the player base this statement is more than likely true, exceptions do exist however such as Lanefan's table and others with a similar playstyle.
I would not go as far as claim any percentage of the gaming community to have or not problems by rolling stats. What I see here where I play is that some folks, like me, were used to need to roll stats just to figure out which classes we could choose, based on those infamous prerequisites. Back then, we didn't plan too much ahead, or we had several different concepts in mind already, and making the rolled stats work was part of the challenge/fun. Also, winning the stat lottery was exciting.
There are others who were really upset about the inability to plan ahead, or that planned either way and sometimes got what they wanted/needed for their concept but sometimes they didn't. For some of those folks, array or point-buy seemed to solve their problems, except some also enjoyed winning the stat lottery, so there is always that.
Bottom line is, we are beating a dead horse for a while now. It really boils down to personal preferences in the decision-making process of building characters for play. Stat-rollers will never be convinced of the benefits of point-buy for a balanced game because they know all the tricks to minimize the impact of bad stats and don't care to play another concept to accommodate whatever luck (or lack of) brought. Point-buyers will never be convinced of the benefits of stat-rolling for character variance because it does limit viable concepts and might hurt balance, specially when you already have something in mind and have to literally hammer on those off-rolled stats in the character sheet and hope it works.
To each their own.
My biggest issue with the point-buy has always been that the ability tables, especially in 5e, are worthless at the odd numbers which means that the gaming table is filled with characters sitting with 10's, 12's, 14's and so forth.
Not enough diversity exists.
I'm working on a house rule to change that and make the odd numbers count too.
I feel the pain too. If you ever find a simple alternative for that, please let me know.
