if you want the literal meaning... It would mean that money can buy you something you really want, but that doesnt mean it will bring you joy. With money, you can get a lot of women... but that doesnt mean that any of them will love you. They would just buy you money. It's also like the saying "Money cannot buy everything."

it means : Money can't buy love.

我猜是这个意思：光有钱而没有爱心，只能得到一只不喜欢你的漂亮小狗。所以引申意思就是：钱不是万能的。
