Yes. All transfers within the Polygon network require the payment of gas in MATIC to make the transfers.
There are several sites that offer a small MATIC balance that allows you to make many transfers. These sites may change their availability over time, and balances may not always be available. You can Google for "Free faucet Matic" to see which ones are available. Here some of them:

A Faucet is a tool that provides a small amount of funds to start using a cryptocurrency without having to buy some.
The term Multi Level Marketing (MLM) refers to a strategy used by some direct sales companies to sell products and services. MLM encourages existing members to promote and sell their offerings to other individuals and bring on new recruits into the business. Distributors are paid a percentage of their recruits' sales. New recruits become the distributor's network or downline and are, in turn, encouraged to make sales to earn money.
Every time a NETU21 Coin holder makes a transaction to another person, the recipient's wallet becomes a first-level member of the sender's network.
The organization of referrals is stored in the same blockchain and is generated as soon as any user (A) sends any number of tokens to a new recipient (B). After this transaction (B) will always be a referral in the first level of (A). (A) will have earnings up to your 21st referral level and he/she can have as many referrals as he/she want on his/her first level. When (B) send any amount of NETU21 Tokens to (C), (C) will be in the first level of (B) and in the second level of (A).
NetU21 Coin tracks downline up to 21 levels for all coin holders.
This implies that every holder of NETU21 is already in someone else's referral network. And it will always be 21 levels.
Currently in any transaction, the destination wallet will receive 99% of the NETU21 Tokens transfer and the remaining 1% is shared equally, in the sending user's upstream network and the receiving user's upstream network. That is to say: that 1% is divided into 42 equal parts and delivered to 21 recipients of the network of the one who sends the tokens and 21 recipients of the network of the one who receives the tokens.
