Yes, that is what he stated. Everything else is guesswork. He's been asked if that means Putin keeps what he's taken and he said no.
No one knows, possibly not even Trump himself has a detailed approach at this point.
Given Trump's focus on China I think it could be increasing pressure on China to drop their support. Make it economically disproportionally costly to keep supporting russia. Also likely a much harsher stance on Iran.
Trump operates outside of predictable political patterns. Anything from withdrawing aid and a congratulatory message to Putin to russian troops getting a text message telling them to "Leave the country within 48hrs or it's Death from Above" is possible.
Unpredictability is an asset, never let others know what you're thinking until actually needed.
... If there is actually any idea to begin with.
Politicians air a lot of empty (campaign) promises, but Trump catches more flak because he's not a darling of the MSM while others have them sugar coated, downplayed or swept under the rug entirely. The 24hrs bit is hyperbole for "quicker than it's going now".
Trump is first and foremost a business man and likes to emphasise his achievements for the US economy. Accelerating the end of the war could mean giving Europe the ability to buy larger amounts of more diverse types of US weapons systems for Ukraine with far fewer restrictions on their use.
That way he supports the US arms industry, the American worker and he gets the Europeans to pay (more) for their own defence. All important for his donors and his voters.
