Does DHCP server take IPs back from sleeping systems before its lease expires?

I have a quick question here: If the IP addresses of a
certain scope are exhausted, how does DHCP server
handle new requests? In such situations, will DHCP
server checks if there are any inactive systems, and
if so, get IPs from these sleeping systems? I don’t
think this is the case. I believe if a lease is not
expired, DHCP server won’t take the IP back for a new
request, even if the IP owner is sleeping at current
time. Is it true?

Thank you in advance!
