There is quite a difference between. exaggeration and blunt lies.
Also most exaggeration happens during campaigns for getting votes, but rarely the result is a strong enough mandate to push all things through, thus one has to compromise ... but campaigning on "well, realistically my options will be limited" doesn't really work, especially as the campaign promises form the negotiation base lateron.
What you point to is an odd reversal for sure. Trump is actually doing many of the things he campaigned on while most candidates lie during the campaign. Trump now lies about seemingly obvious or unimportant things now in office, where many presidents either wouldn't waste a lie on something unimportant or wouldn't bother acknowledging the topic at all.
They all still lie though. Whether a particular lie can be considered an exaggeration boils down to how strict a line one draws around what a lie is. To me, if a president speaks only a partial truth or a misrepresentation if information they very much have access to, its a lie.
He told the truth, but also many lies in parallel. Where is the wall that mexico paid? Where is the peace in Israel and Ukraine? 6 days are over. The truths in between this are useless.
Can you find a president in recent history that didn't fall short of many or most of their campaign promises?
I don't say that to defend trump, the guys is a narcissistic asshole. I only say that to point to the fact that he's doing what any other politician does - say what it takes to get elected then play the game that makes you the most money.

But in that regard Trump is special, also.
