The fact that he didn't really send anything to you becomes more clear when you see him use an emoticon with "tongue stuck out" and even more so when he asks for a photo with your shoe on your head:
OP, can we get a pic of you with a shoe on your head?
Begging for money for the purpose of gambling is generally either ignored or antagonized on this site. People will lie to you and make you waste time just to discourage you from begging in such a way in the future.
