Universal Stats Class for game character/objects

What is the best way to store universal stats that apply to all PC/NPCs in your game? Right now I'm using a solo script with just stat declarations like HP, Max HP, Speed, Max Speed, Strength, etc , all of them int or floats and that's all the script has. The script is pasted on every object in the game.

The other scripts in the project access this particular script with GetComponent. I heard it's a bad thing to use GetComponent too much? And I have many objects getting the stat components from each other. Would it be better to declare the Stat class as a Static Class instead and make all the stats static? Or is there a better way to do all these?
