If you are coding along and not personalizing it, then probably not.
However, you should be making it your own. Employers, prospective freelance buyers are looking for the cool things other companies have, they want to see that you can do them. So you should change what you do with these projects and make them your own.
And if you’re worried, declare it is a tutorial project. For example put my codepen projects in collections and indicate if they came from FCC projects, stackskills, Odin etc. That doesn’t mean I didn’t code them myself, only that I had guidelines I had to follow (which an employer is gonna look for).
Look originality is great, but employer’s are also looking for people who can do the same thing over and over again. It’s part of being a dev.
The really great stuff you do, you won’t always be able to put in your portfolio because you won’t always own it. That’s why you’ll see “I’ve done work for such and such companies” but won’t see examples.
