So, yes, but it can take a little time. The two main things is that a language will meet the needs of its speakers, and that people will have at least one native language. You can't prevent either thing across a group. A new & true pidgin has no native speakers, so no group will depend on it for all of their communication needs, falling back to their native languages when possible/necessary. It will be a native language of the first generation born into its communities. But critically they will also usually be native speakers of another language, the one their parents use at home, and will still be able to fall back to that for some of their communication needs. So the pidgin will grow and change from the use of the first native speaker cohort, but it can take multiple generations for it to have a base of native speakers who depend on it absolutely. Though in other cases, esp with more than two combined languages, it can happen in one generation. And as it's happening, it's fuzzy on whether it's a pidgin or a creole. I don't think linguists consider them separate non-overlapping categories, but more like the two modes in a bimodal distribution. Understanding is also complicated by the fact that these emerge relatively rarely, and tend to be in groups & parts of the world, until relatively recently, without a lot of scholarly attention on them.
