Using kits for web designs

So, today I was searching the internet and found that some of the websites are selling Web Design UI kits (such as Creative Tim) for web designers and I am thinking of buying one. They have pre-built components and styles of certain elements in the kits. My question is are these UI kits are okay to use in the client’s projects. I am new to fiverr and sorry if it is a dumb question to ask :confused:
