How do people actually get scammed after an ICO sale? Let's say i've gone through the company's website, whitepapers and github source codes. I have decided to invest for some of their tokens. Is there a way i scammed after all this? Share your thoughts.

I think so. Scammers nowadays have also made their quality a bit higher to legitimately compete with those projects that are truly legitimate. That is why telling which one is truly legitimate and which one is just wearing some masks is getting really hard to do. However, more or less, after reviewing everything thoroughly, you are removing a large portion of the risks involved. Of course, you cannot make your decision risk-free but at least you are investing in something that passed your screening.
