First time tank with live plants

Hi! I have a fish tank that I want to set up. I decided to add live plants this time and found this bundle of plants on Etsy that I’m going to buy and set up. The tank is a five gallon and if the plants take up too much space I have a 3.5 I can add them in. I have gravel , a heater , and the light that comes with the fish tank. It says I don’t need CO2 and that these plants thrive under low light so I think the light that comes with the tank is good enough. My question is if that’s all I need to start getting it ready? Or should I buy plant substrate supplements/nutrients ? If so which ones do you guys recommend.

Thank you in advance for the help!!
