There are many ways that you can tailor the trackpad to suit your needs best, but at the end of the day, you also need to only touch the trackpad when you need to use it.
I just upgraded from a 2013 model to the 2017 model MacBook Pro, I have tap to click and secondary clicks enabled, I use it at a desk, on my lap, in bed etc and never have any 'miss' touches of the trackpad. But that is just my usage, not anyone else.
If I were you, I would try changing settings in System Preferences > Trackpad to see what works best for you.
Try turning off Tap to Click setting. Then you need to press down on the trackpad until you feel the click to accept it.
Try changing the Secondary Click setting. You can set this to only occur in one of the corners. But if you turn it off completely, you can still get the secondary click by holding the Control key when you click.
You can also disable many multi finger gestures in the 'Scroll & Zoom' and 'More Gestures' panes if they don't work well for you. Most, if not all, have keyboard equivalents that you could use instead.
System Preferences > Accessibility also has more trackpad options. (no idea why Apple put some of these here), but enable the dragging setting can be useful for some too.
You need to find what these combination of settings works well for you. Everybody is different and there are many options available.
However, at the end of the day, the use of any computer has to be fit for your purpose and everyone has a different purpose. If you can't find a combination that works well for you, I would suggest that the model computer that you have purchased may not be fit for your purpose and you may need consider an alternative.
