I am 70 years old. I have a Roth IRA that I made contributions and rolled over amounts from my traditional IRA. Can I withdraw any amount without tax or penalty?

If I read the IRS rules correctly since I meet the 59 1/2 years old and the 5 year since inception (Roth IRA opened in 1999) rules, I should be able to withdraw any amount, including the amount I rolled over in 2016, and any earnings thereon without tax or penalty. Is that correct? If not, what am I missing?
