i am not doing it to be rich

i was looking this site https://bitcoinwisdom.com/bitcoin/difficulty

i think i am doeing it wrong
 46usb X 330kh/s = 15180kh/s
when i put that in the bitcoin calculator it gave 0.0004144usd a day
but when i put it in the litecoin calculator it gave 23.1usd a day

can that be right or have i misunderstood this......
