So the page you linked has the old stats additions. If you look at high elf, the old way would give them +2 dex +1 int as a racial. Now you get to choose what stat gets +2, and what stat gets +1.
Again, the races still get all the other bonuses locked to them. On the BG3 Wiki, High Elves still get:
Darkvision,
Keen Senses,
Fey Ancestry,
Longsword Proficiency,
Shortsword Proficiency,
Longbow Proficiency,
Shortbow Proficiency, and 1
High Elf Cantrip.
I thought I have seen you post in a DnD or the Pathfinder game thread, but just in case you are not familiar with it:
All stats start at 10 with 27 points to use to increase those to a max of 15. The more you increase the stat, the more it costs. You can also "dump" stats that are irrelevant to the class down to 7 to get more points to increase the stats you want. What the "racial" stat additions allow, is the ability to increase one stat to 17, and a second stat to 16 (if you want), instead of the cap of 15.
Point distribution for a wizard w/o racial stats:
STR: 8
DEX: 14
CON: 14
INT: 15
WIS: 12
CHA: 8
Point distribution for a High Elf wizard before the change (current PnP):
STR: 8
DEX: 16 <-- 2 points forced here
CON: 14
INT: 16 <--- 1 point forced here
WIS: 12
CHA: 8
Point distribution for a High Elf wizard after the change:
STR: 8
DEX: 15 <-- you chose to put 1 point here
CON: 14
INT: 17 <-- you chose to put 2 points here
WIS: 10
CHA: 8
