If there is no manual charge for cash, can't you get change ?

Yes
Self-service payment channels also accept cash, which is inserted into the slot and change is given. However, large denomination bills are not accepted. Alternatively, you can use the manned payment channel, which is indicated by signs on the large beam at the toll booth. However, some toll booths do not have manned payment channels.
Can definitely make change if manned, the key is that many places don't have it, and automatic coin insertion can only accept several denominations of banknotes, I forgot which ones specifically, but 10 yuan is definitely one of them. Change is always made in coins, a handful,
Cash can be exchanged for change.
