Nope, same thing, different words used
The idea is it’s more personable, instead of subbing to a Patreon or doing a one-time PayPal or what have you, you “buy them a coffee” or “buy them a pencil” or some other low-cost item that most people both understand helps people AND are cheap/something they might get themselves, so they’re more likely to donate
Also I’m p sure Ko-Fi has a better revenue split with those who use it than Patreon does
You don’t need it, but its a convenient website to let people save their info and support people financially across multiple professions all from one account
Many creators use PayPal or similar to let people just one-time pay through said creators site or app, but Patreon/Ko-Fi/etc. Allow a little more without needing to do all the work yourself
