40/20/3 means he'll limp 20%, raise 20%, and 3bet 3% of the time. The 3rd number isn't bet/4bet, so both the 2nd and the 3rd lines of stats are both wrong.

To take an example:

This is a 40% range:
44+,A2s+,K2s+,Q4s+,J7s+,T7s+,97s+,87s,A3o+,K7o+,Q8 o+,J8o+,T9o

And this is 20% for raising:

66+,A4s+,K8s+,Q9s+,J9s+,T9s,A9o+,KTo+,QTo+,JTo

So the limping range theoretically would be hands in the first set but not in the 2nd set:

44-66, A2s, A3s, K2s-K7s, Q4s-Q8s, J7s, J8s, T7s, T8s, 97s+, 87s+, A3o-A9o, Q8o, Q9o, J8o, J9o, T9o

However, he's more likely to limp hands like 34s than Q4s, and more likely to raise A9o than Q9s etc
