Would you be arrested? Probably not, but you're more likely to be than Trump. See, committing a crime isn't the only factor that influences whether or not you get slapped with the punishment for that crime, even if it's plainly obvious to everyone you committed it. Another major factor is whether or not someone is going to go through the effort of ensuring you get punished - if nobody does, or if they try, but can't get to that finish line of getting a judge to declare you to be guilty in court, then you walk away scot-free.

So, the thing that's keeping you from being arrested is your relative insignificance. You're just some person, so it's unlikely that anyone will go through the trouble of ensuring you receive the punishment for the crime you committed, even if it's a relatively easy thing to do. Now, if you were to go on TV and say it, that would significantly increase your risk, since now more people are seeing you and someone who gives a shit might decide to go after you. That would be damning for you, since it would require very little effort to punish you - you clearly committed the crime, and you have no way to influence the court to make you harder to punish.

For Trump, his protection isn't insignificance - there are plenty of people who would like to ensure he's properly punished; instead, his protection comes from making it really difficult for someone who wants to punish him to be successful in that endeavor. He has a lot of money and influence, so he can hire good lawyers that can drag out the expensive legal process - something he can afford, but a lot of people who might try to go after him can't. His lawyers are also good enough to find loopholes in the law to avoid punishment, so even if you can afford a cheap lawyer for a long time, he'll likely still walk away unscathed. He's also shown that he has the ability to influence what judge gets put on trials he's a part of, which is another factor that influences whether or not he might get punished for the crime.

Ultimately, you'd have to have a rock-solid case presented by a team of very good lawyers working non-stop for months to years in order to bring Trump to justice, and the only people who reasonably have that power are almost exclusively on his side to begin with. Trump has knowingly committed multiple major crimes, and has shown that he has the ability to prevent them from hurting him, so he knows that he has virtually no chance to be punished for minor crimes, and commits them openly all the time.
