Line out to audio interface will work. However the sound quailty is limited by the inexpensive ceramic cartridge found on cheap suitcases and all in ones.

A better turntable worth digitizing with will have at least the white diamond tip AT stylus on an MM moving magnet cartridge connected to a built in RIAA phono preamp for better sound quality.

For a low budget you could upgrade to one of these $129 turntables on sale for $49:

• iLive ITTB1000B
• VPRO-3100

Next step up is an AT-LPW30TK $249 $175 with better build quality and components. Or AT-LP120X $299 if you want that style.
