It is difficult to provide anything but a broad answer to this question as there are very few details.
It seems likely from the context of your question that you would be an international application to the US or Canada. In this case the first issue is funding, or more precisely who will pay for your funding.
In the humanities scholarships or other means of supporting students (such as institutional or supervisor support) are very limited and tuition can be quite high, depending on the location of the school. In Ontario, tuition fees for international students are around ~CAD$ 25k, and many state schools have comparable levels (tuition and related fees vary quite a bit by state or province). As a result, schools accept only a very small number of international applicants because there’s no $$ to support them.
In the STEM, grants are more common but grants are not infinite and faculty prefer to fund in-state or domestic students simply because these students require less support.
If you applied to schools in Ontario, the situation is far from rosy at some of them and schools are looking to pause admission, and possibly close programs. (Although this piece is about undergrante and MSc programs at one specific university, it should reflect an overall malaise in the funding of universities in this province.) Laurentian University in Ontario filed for bankrupcy a few years ago. There are rumours circulating that some schools will offer no entrance scholarships to Canadian students this year. So if you applied to schools in Ontario, you might be a casualty of the financial crunch of these institutions, irrespective of how good you are as a candidate.
Overall, applying “cold” to universities as an international student is now a much more difficult proposition since few departments and supervisors are now inclined to takes chances on unknown candidates.
