wrong...sorta?
The rng rolls are based on the dice + MC relevent stat/10 (so 27 agility is a +2 bonus if agility is required because it's rounded down) - corruption/10.
with high enough stats (Milk, does a body good) rng becomes a complete non-issue.
so the further into the game you are, the higher your stats, the better.
If you want to raise stats, you need to buy the mama maker, which allows you to milk monica at rest spots (early on she needs to be asleep, but high affection she will do it willingly, and if breasts are at 50+ development, you can get 2 Milk... so every rest stop becomes a free +2 to all stats at that point)
