Hello Learning2tractor, Yes, ANY tractor can roll (so can cars)if you do things badly wrong.
Learn about "Centre-of-Gravity" and how it effects tractors
Things YOU can DO to POSITIVELY affect a tractors stability:ADJUSTABLE RIMS, set them wide, positve "arseometer" feel.
Fill rear tyres with liquid
ballast.
Dual rear wheels, gives more width than single rear wheels (no need to dual up the front wheels on compact tractors).
Learn how ballast effects the balance of a tractor, ie heavy brush hog on rear and suitcase weights on front so you can steer properly.
Keep front end loader low to the ground.
Things YOU can DO to NEGATIVELY affect a tractors stability: Drive with loader up high (raises centre of gravity making it easier to roll). (common mistake).
Carry heavy load in loader up high, makes it VERY easy to roll
Carry attatchment on 3 point hitch at maximum height(raises centre of gravity making it easier to roll).
Make sudden sharp turns with raised loader and/or attatchments(INCLUDES FLAT GROUND, not just slopes).
The single most important item is CENTRE OF GRAVITY, learn and understand this and how it affects a tractor and how to keep the C of G INSIDE your wheels.
Lastly this is a psycologically safe(you won't be flamed for ignorance), place to learn as EVERYONE on this forum started out with zero tractor knowledge at some stage, and learned by asking questions and gaining practical experience. In time you will be advising noobs
Good Luck
