Yes, we should not click on unknown links on different websites as some websites are made to install trojan or malwares into your system without any human intervention.
However. there is no harm in clicking the google form link but if you filled the form, provided the private key, and submitted the form, then you are in big trouble as then another person can move your funds to his own wallets.
Some crypto users are so interested in getting some free that they will fill up such forms without any verification and give them important information. The scammer may have already gotten some private keys, because those crypto users do such things as fast as they can in the hope of getting free.
