The meaning of 'Topf' (pot) is almost always clear from context. Words like 'kochen' (to cook) or 'Herd' (stove) point to a cooking pot, 'Pflanze' (plant) or 'Erde' (soil) to a flowerpot, and 'Geld' (money) or 'Förderung' (funding) to the metaphorical meaning.
Wir brauchen Erde, um die Blume in den neuen Topf zu pflanzen.
We need soil to plant the flower in the new pot.
In connection with cooking, 'Topf' (pot) is often combined with certain verbs. Typical actions are to 'auf den Herd stellen' (put a pot on the stove), 'vom Herd nehmen' (take it off the stove), or 'im Topf kochen' (cook something in the pot).
Kannst du bitte den Topf mit der Suppe vom Herd nehmen?
Can you please take the pot of soup off the stove?
In the figurative meaning, 'Topf' (pot) stands for a budget or sum of money that has been collected for a specific purpose. People often speak of a 'Fördertopf' (funding pot), 'Geldtopf' (money pot), or 'Lostopf' (lottery pot).

The sentence 'Jeder Topf findet seinen Deckel' (every pot finds its lid) is a well-known German proverb. It is used to express that there is the right partner for everyone.

'die Kasse' and 'der Topf' can both mean, in a figurative sense, money that is available for something. 'Kasse' sounds like the available funds of an organization, club, or project. 'Topf' more often means a specific budget for a fixed purpose, from which money can be taken. The words can be confused because in both cases you are talking about money. 'Kasse' is more natural when it is about the general amount of money available; 'Topf' fits better when money is clearly reserved for a specific area.
