ETH Faucets

Im new to crypto and i know that there is a solana faucet that gives you 0.000001 SOL every 24hr but i just saw some RINKBEY and GOREIL ETH faucet websites and i dont really understand what is testing ETH and how is it different from regular ETH. Anyways the website didnt give me the ETH due to an error so if someone could send me some (if it works for you) this is my wallet address: 0xBf5017426eB1e5df81eAFaB228fF6E109cc60942
