Whether something is countable or uncountable takes time to learn and can only be achieved through longterm exposure to English. Also, what may seem logical in your own language may seem completely illogical in English! Learning a language involves learning another culture's point of view, and as always, the guidelines above should be used to help your own understanding rather than as hard and fast grammar rules. Good luck!
