Most scholarship providers will ask for a distinction but, in some cases, merit in your master’s.
With a pass, getting a PhD scholarship won’t be easy.
Since you did your masters in the UK, you might have a chance, but that will depend on your undergraduate degree performance (if you attained at least a 2.1) and the strength of your PhD research proposal.
If certain mitigating circumstances affected your performance (e.g. health challenges), you can include this in some scholarship applications along with evidence.
