There’s golden statues throughout the game. All give you +1 extra status point.
Also, every few stats added in a certain stat give you a bonus stat, that’s why you’re seeing more on tosbase, most likely.
If you carefully add point by point, you will notice when it increases by 2 (sometimes even 3) instead of just 1.
That’s why adding few points into every stat at the beginning to reach the first stat bonus is good, because some stats at the beginning are very close to the double gain. (Different for every class, of course)
Well, of course, you shouldn’t get int bonus at the beginning on a swordsman, obviously.
