Pop-up tips can be helpful for new users. Using language like "Got it" strikes me as overly casual or dismissive, and reminds me of the bossy interruptions that Google uses in their G-suite. Most frustrating for me is when I'm trying to complete a task, only to be interrupted by a pop-up, which includes some tip that I don't understand. I would prefer to have a tip be an "opt-in' experience, with the screen giving me an indication that there is a tip available for a nearby control, if I have the time and interest to explore it. Then, if I choose to open the tip, it would be useful to include a help link, in case I don't "get it", and want a more in-depth explanation.
