'Man' looks like the English word 'man', but it has a different meaning. It is an impersonal, gender-neutral pronoun corresponding to 'one', 'you', or 'they' in general statements.
In Deutschland trinkt man gerne Bier.
In Germany, people like to drink beer.
The verb that follows 'man' is always conjugated in the 3rd person singular, just like with 'er', 'sie', or 'es' (he, she, or it).
Hier darf man nicht rauchen.
You are not allowed to smoke here.
The pronoun 'man' exists only in the nominative. If you need an accusative or dative form, you use 'einen' (accusative) or 'einem' (dative).
Die laute Musik kann einen wirklich stören.
The loud music can really bother you.
I
'ich' and 'man' can both be the subject in a sentence, but they do not mean the same person. You use 'ich' when the person speaking is talking about themself. You use 'man' for general statements, rules, or recommendations when no specific person is meant. Learners may confuse the words when talking about their own experiences that could also be true in general. If you really mean yourself, 'ich' fits. If it is about people in general, 'man' is more natural.
