The way stats (“ability scores”) work in 5th edition with the point buy system is that everything caps at 15 unless racial bonuses are involved.
And even through level ups and feats you can’t raise any stat above 20.
Personally I hate dice rolling for stats. It can be either incredibly unfair to different players or borderline a cheat when you can re-roll as many times as you want completely unchecked by a DM supervising the process.
