From the youtube comments:
That's not what it meant in the context. He planned to be the president 2016-2024, but the FIFA events were planned for after 2025. That's why he says that it was sad, as he wouldn't be able to be the president because he would have already served the maximum of two terms. But he lost in 2020 (He accuses Democrats of rigging the election), which let him partake and win 2024 election, so he will be the president during the FIFA events. So he isn't admitting to having rigged the election, instead he still claims that the 2020 election was rigged against him.
I do think that the election was either rigged or at least Trump believes it was. He admitted to Musk tampering with votes is Pennsylvania live on stage. I'm also convinced he'd happily admit it again. But I don't think this one is another confession.
