just a question

Yes.
New tattoo will have that look – then more skin will grow or heal over it and it will soften and look more subtle. It might also vary in color – some pigments will fade a bit – while others will seem to brighten up.
Better to “not go deep enough when tattooing” then to go way too deep…
Check with the artist who is teaching you –

You don’t have any tattoos of your own do you???
If you had a bunch of tattoos – then you could see the healing process first hand – obviously.
You could also watch a professional in action.
