If you think something is possible in the future, you are making a prediction.
I think England will win the next World Cup.
These are the most common expressions for making predictions. The percentages (%) are very approximate - just to show you the order of the expressions.

It'll almost certainly rain. It's bound to rain.
90%-99%
It'll probably rain. It's likely to rain.

Notice the position of words like "definitely" - before "won't", but after "will".
We sometimes use '(to be) going to' instead of 'will' for predictions. ‘(To be) going to' can mean that we have a reason or some present evidence for making the prediction:
I think it'll snow next Christmas.
(but that's in 12 months - I can't know this)
I think it 's going to snow again tomorrow.
(there are a lot of clouds and the weather is very, very cold)
