Uhm not really. (Sorry long text, read if you want i guess)
Spanish could be useful as well.
Almost 0.5 billion people out of 7.7 billion speaks Spanish.
French gets spoken all over Carribean (French West Indies etc) & Africa, parts of Canada as well as in Belgium (Belgium speaks Dutch, French & German though) & France (Duh)
274 million French speakers back in 2014, so they are probably around 282+ or something rn, thats almost 0.3 billion.
So just French & Spanish is about 0.9 billion out of 7.7 billion.
Then also arabic etc languages: 0.41 billion + some African & Asian countries which is about 0.21 billion, so in total 0.62 billion speaks Arabic.
So French, Spanish & Arabic speaking people = 1.52 billion, thats a little bit less than 1/5 of the population of planet earth lol (isch).
So if anything languages that are "needed" is Arabic, English, Spanish & French (& Manadrin Chinese) lol.
But yes, English is probably the "easiest" way of talking with X person from X country if you dont speak Spanish/French/Arabic/Mandarin etc.
Mandarin Chinese is super useful as well if you live/visit there since 1.1 billion people speaks it as well & obv 1.1 billion people is about 1/7th of the earths population.
