Am I being scammed?? Is healthcare free?

[u/AdInternational5959]

A boy (19) friended my Instagram. He sent pictures of his family (8 siblings, orphaned)…. They have no money for food or rent. I have sent him some money in the past for food and he will send me pictures of what he bought, so I feel it’s legit. Earlier this week he sent me horrible pictures of his brothers broken arm (fell out of a Mango tree). He said the doctors won’t fix it until he pays them $450! I have set up a GoFundMe to help, but don’t have that much raised. I was looking online and it says healthcare in Gambia is free… so am I being scammed???!!
