No they are not.

[infographic]

While, your overly used infographic is correct in saying that it would be impossible to check all of the keyspace, it doesn't necessarily mean it's impossible for someone to bruteforce a private key. It may be extremely and ridiculously unlikely but there is still the minutest chance that one can be found via bruteforcing. But for all intents and purposes that probability is so low that we just like to say its impossible because it sounds better.

The term is infeasible. Then again just about anything which most people consider is impossible is simply low probability. Trying running directly into a wall. There is a non zero percent chance that due to quantum effect you will pass right through it.
