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......

You're purchasing SHA ASIC, they work for Bitcoin mining only, not Litecoin mining.
So 0.0004144 USD/day is the correct figure, considering the current difficulty.

I wouldn't advice purchasing a shitload of USB miners even if you're doing this for fun.

Instead consider purchasing ONE Gridseed ASIC miner which works with Litecoin. You'll have fun and a considerable return on your investment too, at least for a few months.
