What he is saying is totally baseless. First of all, the nisab of gold is 85 grams. Secondly, the zakat is paid over the whole amount. This means that your zakat is 5 grams of gold.

Zakat can only be given in cash to the poor and needy. If he fits the description, you can give him from the zakat.

You give Zakat on whatever gold and silver, and money you have in your bank account at the end of a lunar year. Money is treated like silver in regards to the threshold which is the value of 595 grams.

Zakat has to be in cash or they authorize you to buy them something specific.
