I think countries using Latin words will get more advantage in mastering English. I just see countries that use different alphabet like Japanese, Korean, Thailand may get more difficulty in learning the language despite these nations relatively are good economically. Their people are rarely found in internet world and usually the ones who are active are their overseas community.
Definitely for reading and writing, its a big leg up if you already know the latin script from own language, the basic sounds etc do not change much between languages.
Spoken wise, you need people to speak to and that can be an issue ofc for any language, whatever its writing system.
