Are cycloalkanes isomers of alkanes?

Yes, that is right.
Yes, that is right.
I might not fail a level chem next year!

I know it may seem a dumb question, however, are cycloalkanes classified as alkanes? Or are they classified as alkenes?

Alkanes I think

They are alkanes. Clue is in the name - cycloalkane.

Cycloalkanes have the general formula CnH2n.
Cylcoalkanes are not alkanes.

This is wrong. They are a type of alkane actually because they are saturated, hence the name cycloalkane. They have no carbon - carbon double bonds. Hence do not have a reaction with bromine water, and do not turn it from brown to colourless. This mean they fit the definition of an alkane. They may have a different formula, but due to their saturation, they are alkanes.

The definition of alkane vs cycloalkane does not depend on properties.
IUPAC defines alkanes as "acyclic branched or unbranched hydrocarbons having the general formula CnH2n+2, and therefore consisting entirely of hydrogen atoms and saturated carbon atoms"
Do you know what acyclic means?

Would they be considered as a saturated hydrocarbon then, of which cycloalkanes and alkanes both are?

In year 2 A level chemistry you’ll learn about unsaturated alkanes, specifically benzene which is a super interesting molecule and has many unique properties.

The name cycloalkane probably comes from the fact that they have similar properties and reactions to alkanes, but they aren't themselves alkanes.

To use your words against you:

I believe I may stand corrected. In any case, in an exam if you’re asked what type of molecule a ringed saturated hydrocarbon is, the answer would be cycloalkane.

Well no, because alcohols don’t only contain carbon and hydrogen

Chemistry is all about pedantic definitions and this is an example. Just because a name suggests one thing, doesn't necessarily mean it means it.

Your earlier description of alkanes did not include reference to C and H.

Wait, then why does this say they are? It’s a pretty reliable source

Your source contains a mistake, therefore.
