It's difficult to add to what ImOnlySleeping said, but I think it's worth noting that if you have little to no experience in making pro quality kick, hat and snare samples then you're going to have to accept that there's going to be a lot of practice needed in order to make them.
I agree that you can get some unique sounds out of sampling different things. It's fun, it's effective and it can often sound really fresh in a track. I do it a lot. But if you're focused on creating sounds that actually sound like pro kicks, hats and snares instead of just percussive sounds focused in that frequency space then it'll be a lot of work. I'll always encourage people to become the best they can be, so all I can really say is best of luck and keep at it.
The samples that you get in samplepacks are only created by humans with production skills, so you should be able to do it eventually too.
