Black moves first, on a 3x3 and 5x5 both end up 100% black with any white piece being captured. Many other board shapes don't but Go is played on a 19 x 19 board. We don't know about 9x9 or even 7x7 so the pattern is hardly set in stone. Still it seems likely.
Now, with a perfect white play there may be moves an imperfect black player makes which causes white to attack. But, perfect play on both sides probably means any white stone gets captured so white plays zero stones.
