In fact, the above are the conditional sentences (type1&2)
See the following example:
Type1: If I don't eat anything, I will feel hungry.
This type is talking about things that MOST PROBABLY will happen, or we expect that the events WILL HAPPEN, like the above example, it is likely that if I don't eat anything, I am SURE that I will feel hungry, so we use type 1.
Type2: If I won the raffle, I would donate money to the charity.
This type is talking about things that ARE NOT LIKELY to happen. See the example, we know that it is not easy for us to win the raffle, so we use type 2 in this case.
