Correct on both counts. However, under Trumpcare if you choose not to purchase health insurance now, you will be penalized later on when you do decide you need it.

And you will need it, unless you are independently wealthy, you most certainly will need health insurance eventually.

But you won't be paying the penalty to the government, as is the case with the ACA, you will pay your penalty to the insurance company of your choice, if you can afford it.
