in short, it reads across as ‘one-hundred percent’, meaing ‘the most’.

1)full effort; all; maximal exertion (as applying to a sport, usually)

2)completion (commonly of a particular RPG):
a] in utterly the sumpremest, truest sense of the word;
or
b.] virtually, or for intensive or practical purposes (can vary)

Note that that the second use of ‘100%’ can serve as many parts of speach simply by adding a different suffix.
{100% = completion to the fullest extent}
100%ly = adverb
100%'r or 100%er = person (noun)
100%'d or 100%ed = past-tense form of verb (usually transitive)
. . . and so on . . .
