Yes, many (but not all) of the top journals are closed.

A lot of scientists talk big when it comes to open access, but when it comes time for them to publish their own work, they published in closed journals since they have a bigger impact factor.

The publishers want to have some financial income from your papers. So if you want a paper to be openly accessible, so preventing them from a future income from that paper, as an author you will have to pay their potential incomes, and this can cost up to 3000$ per publication.

That is a substantial sum even for professors from wealthy countries.
